HMT Technology Corporation ("HMT" or the "Company") is an independent supplier of high-performance thin-film
disks for high-end, high-capacity and removable hard disk drives, which in turn are used in PCs, network servers and workstations.
HMT was incorporated in Delaware in December 1988 as a subsidiary of Hitachi Metals, Ltd. ("Hitachi Metals") to acquire certain
assets and certain liabilities of the thin-film division of Xidex Corporation, which had been producing thin-film disks since
calendar 1983. Since completing the acquisition, the Company has continued to supply thin-film disks to manufacturers of hard disk
drives.

The disks currently being shipped by the Company are primarily for disk drives and removable cartridges with
storage capacities ranging from 1.0 to 40.8 gigabytes (using one to four disks), and all have coercivity levels of 2100 Oersted or
higher. Since March 1994, the Company has focused on addressing the needs of the high-end, high-capacity segment of the disk drive
market as well as the removable and emerging low cost hard disk drive segments. HMT believes that its current operating results
reflect its success in meeting these needs and that its future growth and success depend on its ability to continue to develop and
market products that enable its customers to produce high-performance disk drives for high-end data storage applications. The Company
provides a range of magnetic density points (coercivities), glide heights, disk thicknesses and disk sizes to match the design and
performance requirements of each particular customer. The Company's principal customers currently include Maxtor Corporation
("Maxtor"), Western Digital Corporation ("Western Digital"), Iomega Corporation ("Iomega"), Samsung Electronic Company Limited
("Samsung") and Conner Corporation ("Conner").

In April 2000, the Company entered into a definitive merger agreement with Komag, Incorporated ("Komag").
Komag designs, develops, manufactures and markets high-performance thin-film disks. Under the terms of the definitive merger
agreement, each issued and outstanding share of HMT stock will be converted into 0.9094 shares of the Komag's common stock. The
merger will be accounted for under purchase accounting and is subject to customary closing conditions, including regulatory
approvals, the approval of both companies' shareholders and the Company's lenders. The merger is expected to close in the third
quarter of calendar 2000.

Investors and security holders are advised to read the joint proxy statement/prospectus regarding the business
transaction referenced in the foregoing information, when it becomes available, because it will contain important information. HMT
and Komag expect to mail a joint proxy statement/prospectus about the transaction to their respective stockholders. Such joint proxy
statement/prospectus will be filed with the Securities and Exchange Commission by both companies. Investors and security holders may
obtain a free copy of the joint proxy statement/prospectus (when available) and other documents filed by the companies at the
Securities and Exchange Commission's web site at http://www.sec.gov. The joint proxy statement/prospectus and such other documents
may also be obtained from HMT or Komag.





Industry Background

The Disk Drive Market

Market demand for disk drives has been growing steadily, stimulated by the demand for new computers, upgrades
to existing computers and the growing use of sophisticated network servers.The introduction of increasingly powerful microprocessors and more memory intensive software, combined with the development
and growth of multimedia computing applications and Internet usage, have stimulated demand for PCs in both the home and business
markets. According to Trend Focus, worldwide shipments of PCs were 90 million units in calendar 1998 and 109 million units in
calendar 1999, and are projected to reach approximately 216 million units in calendar 2003. In addition, the PC server market, driven
by the trend toward networking applications and the expansion of the Internet, is expected to grow substantially through the calendar
year 2003. Although unit shipments of PCs are expected to grow, the introduction of the sub-$1,000 PC has had far-reaching effect
throughout the PC supplier base. As PC prices have fallen, the pressure on key component manufacturers, such as disk drive
manufacturers, has intensified.

This pricing pressure was evident in calendar 1999; according to Trend Focus, worldwide shipments of hard disk
drives grew 20% to 174 million units in calendar 1999while revenues remained
flat from 1998 at $25.9 billion.Analysts predict that drive unit shipments
will continue to grow at a 16% annualized level through 2003 to 316 million units while average sales prices are expected to fall off
at approximately 5.5% annually resulting in $32 billion in revenue by 2003. Although calendar quarter four showed a reduction in
corporate PC sales, the continued growth in the sub $1,000 PC market and Y2K preparation resulted in increased drive and media sales
for calendar 1999. However, the disks-per-drive ratio continued its decline from 1998 to 1999 falling from 2.15 to a 1.77 average for
desktop PCs. This ratio is expected to continue its drop over the next three years to 1.4 in calendar 2000 and reach below 1.2 by
calendar 2003.

According to Trend Focus, media unit shipments

The applications being developed for PCs require greater storage capacity and, as a result, have increased the
demand for high-capacity disk drives. Users purchasing newer PCs for business and home are commonly attracted by the availability of
greater processing power, larger databases, multimedia and other memory intensive applications and more sophisticated operating
systems, such as Windows 98 or Windows NT. Increasing use of the Internet and on-line data, including image storage and retrieval,
has been responsible for the stimulated demand for storage capacity. The disk drive industry has responded to this demand with
significant technology and product advances. As a result, mean storage capacity per disk drive has increased from 690 megabytes (MB)
in calendar 1995, to 4.3 gigabytes (GB) in calendar 1998, and accelerated to 10.2 GB in 1999. This increase in storage capacity per
platter has enabled disk drive manufacturers to reduce the average number of disks per drive. According to industry market analysts,
this resulting reduction in the average number of disks per drive will likely slow the growth rate of disk shipments below the growth
rate of disk drives during calendar 2000 and beyond. The significant amount of captive capacity employed by certain disk drive
manufacturers also continues to limit the market opportunities for independent disk suppliers such as HMT.

While storage capacity has grown, the cost per GB has fallen from $1,260 in calendar 1993, to $320 in calendar
1995 and to $6 in calendar 2000. Today's market continues to generate pressure for advances to facilitate these trends in computing,
especially at the high-end. Thus, we believe that success in the disk drive market has depended, and for the foreseeable future will
depend, on the ability of the disk drive manufacturer, together with its suppliers of critical components, such as thin-film disks,
to keep pace with these advances.

Additionally, removable-media storage devices, including removable hard disk drives, have an established portion
of the storage market. Removable hard disk drives utilize cartridges incorporating thin-film disks and combine the high-capacity and
rapid access of hard disk drives with the benefits of removability. These devices can be used peripherally to increase the storage
capacity for PCs.

Disk Drive Technology

Fiscal 2000 was a difficult year for the Company and the disk drive industry in general. During both fiscal
1999 and 2000, the areal density (measured in billions of bits per square inch of disk area: (Gbit/in2) of customer
products increased at the unprecedented rate of greater than 100% per year. This has necessitated the development of new disk surface
finishes, new magnetic alloy systems and new tribology at an extremely accelerated pace. In fiscal 2000, the majority of disk drives
were manufactured with advanced giant magnetoresistive (GMR) components. A GMR disk is optimized for use with GMR heads that use
separate read and write elements. The write element is made from conventional inductive materials, but the read element is made of a
material whose electrical resistance changes when subjected to changes in a magnetic field. GMR heads are more sensitive to magnetic
fields enabling them to read more densely packed smaller-sized bits. The transition to GMR and magnetoresistive ("MR") disk drives
has led to significant, unprecedented increases in areal density. HMT Technology Corporation completed its transition to GMR products
by the second quarter of fiscal 2000, and GMR media currently accounts for 100% of our unit sales for fixed disk drive applications.
We believe that GMR disks will continue to be the predominant media for disk drives in fiscal 2001.

Prior to fiscal 1997, market demand for advanced thin-film media typically exceeded supply. In mid-fiscal 1997,
the rate of growth in demand for media slowed abruptly due in large measure to the significant increases in storage capacity per disk
achieved through the use of GMR/MR technology. As a result, drive designs incorporated fewer disks and recording heads to achieve the
disk drive capacities demanded by the market. In addition, based upon historical supply shortages and forecasts for continued strong
demand growth rates, HMT and our competitors (both independent and captive suppliers) began adding significant media manufacturing
capacity in fiscal 1996, which for the most part became operational in fiscal 1997. The increased supply of media generated by the
expanded physical capacity, coupled with the tremendous improvement in disk storage capacity, allowed the overall supply of thin-film
media to catch up to, and then exceed, market demand. Captive media suppliers (owned by vertically integrated disk drive customers)
utilized their capacity at the expense of independent suppliers, such as HMT, during this period. As a result, in fiscal 1998, fiscal
1999 and fiscal 2000, the market for disks produced by independent suppliers decreased sharply and pricing pressures intensified.
During fiscal 2000, we idled certain equipment and facilities to more closely align our production capacity to demand for our
products.



The basic elements of the disk drive, sized to fit various industry form factors, have remained essentially the
same since hard disk drives were first introduced. The principal components of a hard disk drive are disks, heads, spindle and
actuator mechanics and electronics. Each disk drive typically contains from one to ten disks that are attached to a spindle/motor
assembly within a sealed enclosure. The electronics control the spinning of the disk, the positioning of the head and the writing and
retrieval of data stored on the disk. The recording head is a small magnetic transducer that, when the disk is spinning, "flies" just
above the disk surface. Data are written on circumferential tracks on the disk when the electronic channel sends current pulses to
the head. The head converts these pulses to magnetic fields that cause the magnetic layer within the disk and under the recording
head to become magnetized, oriented in the direction of the head's magnetic field. Reversing the current in the head reverses the
direction of the magnetic field on the disk. During the read-back process, as the head scans over the disk, magnetic flux from the
disk's magnetic layer is picked up by the head and induces an electrical current which is converted into voltage. The output signal
voltage is then transformed into digital data by the read channel electronics.

Major improvements in disk drive performance have been based on technological advances in the principal
components. In a typical disk drive today, the spindle/motor assembly rotates the disk at 5,400 to 10,000 revolutions per minute. The
head reads and writes data onto the spinning disk while flying at a height of 0.8 to 1.2 microinches (0.020 to 0.030 micron) and at
data transfer rates of 250 to 350 megabits per second. The combination of modern head and disk technologies enables this drive to
store data on 17,000 to 22,000 circumferential tracks per radial inch on the disk, with 300,000 to 380,000 bits of data per inch
along each track.

Thin-Film Disk Technology

A thin-film disk is composed of a substrate, generally aluminum, coated with thin-films capable of storing
information in the form of magnetic patterns. The manufacturing of thin-film disks is a multi-step process using processes similar to
those used for the production of silicon wafers for semiconductors. The manufacturing process involves the deposition of extremely
thin, uniform layers of magnetic film onto a substrate using a sputtering process, by either a static or in-line system, similar to
that used to coat silicon wafers. The basic process consists of many interrelated steps and requires an extremely clean environment.
Minor deviations in the manufacturing process, minute impurities in materials used, particulate contamination or other problems can
cause significant numbers of disks to be rejected, thereby causing significant yield loss.

The most significant technological challenges facing disk manufacturers today are associated with market demand
for increased storage capacity and durability. An effective implementation of thin-film technology to meet these challenges must
address various performance-related characteristics, including magnetics, glide height, durability and static friction
(stiction).

-	Magnetic Coercivity, a measure of the magnetic strength of the disk, is expressed in Oersted (Oe). The
coercivity of the disk is determined by the types of disk substrate and thin-film materials used, substrate surface conditions before
disk sputtering and the conditions that exist during the sputtering process, including temperature, vacuum and possible sources of
disk contamination. As areal density increases, higher coercivity is needed to permit sharper transitions between magnetized regions.
This allows each bit of data to be stored in a smaller area, and therefore more data can be stored in the same disk area. Advanced
drive designs currently require coercivities in the range of 3200 to 3400 Oe, compared to a range of 950 to 1200 Oe nine years ago.
We believe that most high-end disk drive manufacturers will require coercivities of 3200 Oe and above by the end of calendar 2000.
HMT currently manufactures and sells disks in commercial quantities with coercivities ranging from 2100 to 3300 Oe, with over 80% of
our revenues during the three months ended March 31, 2000 deriving from disks with coercivities of 2000 Oe and above. We are also
currently producing small quantities of disks for use in customer development programs with coercivities of up to 3600 Oe.

-	Glide Height. The glide height of the disk is the measure of the height at which the head can fly over the
disk without hitting anything and is a standard used in the specification of the disk. The actual flying height of the head in the
disk drive is higher than the glide height to provide a margin for safety. Glide height depends on the smoothness and flatness of the
disk surface. The lower the disk head flies above the disk surface, the more accurately the head can read the magnetic signal,
allowing a smaller magnetized region to store each bit of data and thereby contributing to increases in areal density. While the
current industry standard glide height for advanced applications is 0.7 microinch, we expect that glide heights will decrease to less
than 0.6 microinches by the end of calendar 2000. HMT currently manufactures and sells disks in commercial quantities with glide
heights of 1.2 microinches to 0.7 microinches.

-	Durability Through Start/Stop Cycles. In most hard disk drives, the head and disk come into contact when the
disk drive is turned off and the head rests directly on the inner diameter of the disk. To prevent wear on the disk, a protective
overcoat is deposited over the magnetic layer of the disk. However, the thickness of this overcoat must be minimized because this
layer increases the distance of the head from the magnetic layer, thereby reducing the strength of the magnetic signal reaching the
head. Customer specifications typically require 60,000 start/stop cycles for desktop PCs.

-	Stiction. Stiction is the static friction that occurs when two smooth surfaces come into contact. In the
case of hard disk drives, an extremely smooth disk surface enables lower glide heights and can enhance durability by reducing the
friction which occurs when the head contacts the disk. However, if a disk is too smooth, stiction will cause the head to adhere to
the disk surface when the drive is turned on and off, causing irreparable damage to the hard disk drive. Disk manufacturers minimize
this problem primarily through texturizing the disk surface in a controlled manner. Disk manufacturers cannot simply address each
performance characteristic discretely because the interplay among characteristics significantly impacts the overall performance of
the disk. For example, a protective overcoat that yields a highly durable disk may well reduce the disk's potential storage
capacity.

Challenges Facing the Disk Drive Industry

Despite technological advances in components, including thin-film disks, and the prospects for continued data
storage market growth, disk drive manufacturers face a demanding marketplace. A strong competitive position is best achieved through
continual innovation. Improvements in product performance characteristics, designed to meet the growing demands for increased storage
capacity, play an integral part in allowing the manufacturer to generate acceptable gross margins. However, in the highly competitive
disk drive industry, other manufacturers have generally been able to develop comparable products within a relatively short time. The
likelihood of rapidly decreasing profitability over the life cycle of any given product provides a strong incentive for manufacturers
to innovate. This results in extremely short product cycles, currently estimated to be from nine to twelve months.

Disk drive manufacturers participating in the high-end, high-capacity disk drive market segment can realize higher
gross margins by successfully addressing the need for drives capable of supporting today's demand for high-performance, value-added
computing products. In this segment, which supplies products incorporated into high-end PCs, network servers and workstations, users
are less price sensitive than typical home PC consumers because they have a more compelling need for a value-added product. Because
of the short product cycles and the significant technology improvements incorporated into each new generation of high-performance
disk drives, the need to be in the forefront of technological advances is particularly great for companies competing in this
segment.

Disk drive manufacturers can produce higher capacity products by putting more disks in a drive or coupling a
number of drives together in an array. These approaches are limited by form factor constraints and technical complexity. These are
also relatively high-cost solutions since the drive manufacturer is adding more componentry. A more cost-effective solution is to
develop a product that can store more data using the same number of components. Thus, disk drive manufacturers generally have relied
on the development of new head technologies and of thin-film disks with improved areal density characteristics to support
generational advances in storage capacity and performance.

HMT focuses on providing value-added technological solutions that meet the demands of the high-end, high-capacity
disk drive market. We develop, manufacture and sell technologically advanced products designed to provide improved performance,
principally through achieving higher coercivities and lower glide heights. HMT seeks to be a supplier to disk drive manufacturers
with a proven record for technological leadership because these customers have the greatest ability to fully exploit the value of
technologically superior disks. By working with such high-end customers and their head vendors, HMT can influence leading edge disk
drive designs and earn a strong position as a supplier of disks for these products.

The key elements of HMT's strategy are as follows:

- Establish and Maintain Leadership in High-End Product Technology. We focus our development resources
principally on performance improvements for disks sold to the high-end, high-capacity segment of the disk drive industry. In order to
improve product performance characteristics, including magnetics, glide height, durability and stiction, HMT is continually engaged
in efforts to enhance its proprietary technologies and processes. Two current examples of proprietary technologies include an
advanced single step, ultra super polish process for disk substrates and an advanced Ion Beam based carbon overcoat deposition
process for ultra thin protective media coating.
- Develop Collaborative Relationships with Leading Head and Disk Drive Manufacturers. We work closely
with head manufacturers developing new technologies, including Giant MR, Proximity MR and "Pad Slider" head compatible disk. This
collaboration enables the parties to develop compatible products that can be effectively incorporated together into leading edge disk
drives. HMT also seeks to establish strong relationships with its customers, enabling the Company to participate in establishing
technological and design requirements for new products. We believe that close technical collaboration with its customers and their
other suppliers during the design phase of the new disk drives facilitates integration of our products into new disk drives, improves
our ability to reach cost effective high volume manufacturing rapidly, and enhances the likelihood that we will become a primary
supplier of thin-film disks for high performance disk drive products.
- Develop Advanced Manufacturing Processes to Support Volume Production. HMT develops advanced
manufacturing processes directly on state-of-the-art production equipment. Developing manufacturing processes for new products
directly on active production lines during the research and development phase increases the likelihood that we can quickly and
efficiently transition to high volume commercial production of new products. The ability to implement new processes quickly also
helps us meet our customers' increasingly rapid time-to-market demands and advances our goal of having our products designed into its
customers' disk drives.
- Maintain Strict Quality Control of Manufacturing Process. HMT believes that its close attention to
quality control results in a consistent product and high production yields and is key to its success. Attention to quality has the
dual benefit of producing high-performance disks and lowering our cost of production. In addition, product quality is an essential
factor in the supplier certification process of disk drive manufacturers.
- Scale Manufacturing Capacity to Meet Demand. In fiscal 1997, we completed construction of a new 124,000
square foot production facility at its Fremont, California site. We brought four production scale sputtering lines into service
during fiscal 1997, six in fiscal 1998, and an additional two in fiscal 1999. This building has capacity for four more lines. During
fiscal 1997, we completed the first phase of expansion of our facility in Eugene, Oregon, commencing volume production of aluminum
substrates and nickel-plated and polished substrates at that site. During the third quarter of fiscal 1999, we completed the second
phase of expansion of the Eugene facility, adding more polishing capacity. During the third quarter of fiscal 1999, we idled seven
sputtering lines and associated equipment and facilities in connection with our restructuring plan.



Products

We provide a range of magnetic density points (coercivities), glide heights and disk thicknesses. HMT
currently manufactures and sells disks in commercial quantities with substantially all having coercivities levels of 2100 Oe or
higher and glide heights of 1.2 microinches or less. At March 31, 2000, 80% of revenue was generated from disks with coercivities of
3000 Oe and above. We are also currently producing small quantities of disks for use in customer development programs with
coercivities of up to 3600 Oe.

Our product mix continually shifts as technological advances are implemented in anticipation of demand for disks
with improved performance characteristics, and we transition production from less technologically sophisticated disks still in active
use. For example, during the three months ended December 31, 1996, 2000 Oe and below products comprised 80% of total units shipped,
as compared with the three months ended March 31, 2000, where 2100 Oe and above products comprised 100% of total units shipped.

Our disks are currently used by five disk drive manufacturers in more than 16 different 3 1/2-inch disk drive
products. Currently, these disks are used in fixed disk drives that have capacities ranging from 7.16 GB to 40.8 GB with storage
capacity per disk ranging from 5.0 GB to 7.25 GB and removable disk drives that have capacities of 1.0 GB with storage capacity per
disk of approximately 500 MB to 1.0 GB. HMT has the technological capability to produce disks
to fit standard form factors of 5 1/4-inches and below, although we currently produce only 3
1/2-inch disks.

Manufacturing and Quality

HMT believes that our internally developed proprietary and patented
manufacturing processes and state-of-the-art equipment, to which we have made proprietary
modifications, combined with its extensive expertise, currently provide HMT with a
technological advantage over competing independent thin-film disk manufacturers. HMT's expertise, processes and equipment also allow
us to develop new proprietary processes in response to customers' requirements for improved product performance and to integrate new
technologies into the manufacturing process rapidly. Our production lines are scaleable and have been designed to be installed,
modified or expanded in a cost effective manner. The use of a modular strategy facilitates incremental capacity increases, efficient
adaptation of manufacturing equipment for new product processes and achievement of high volume manufacturing capacity for new
products on a timely basis.

Manufacturing Process

Our manufacturing process is briefly summarized as follows:

Machine, Chamfer, Bake, Grind and Wash. The initial input to the production of a thin-film disk is an
aluminum blank that can be procured from a number of sources. To create specialized aluminum alloy substrates, HMT machines the inner
edges of the blank to specified diameters, chamfers the inner and outer edges of the blank and bakes the chamfered blank to relieve
stress induced by the machine and chamfer processes. HMT then grinds the blank to achieve required gauge thickness and flatness,
remove surface defects and improve surface finish. HMT then washes the blank to remove particles. HMT currently produces these
substrates through in-house manufacturing, and may from time to time purchase a portion of its requirements from independent
vendors.

Plate, Polish, Texture and Wash. Aluminum substrates are plated with electroless Nickel-Phosphorous alloy,
a non-magnetic layer critical to corrosion resistance that strengthens the disk and improves durability. HMT currently performs most
of its nickel plating in-house. Disks are then polished to produce a mirror smooth surface. Polishing enhances the nickel surface,
reducing its roughness, while maintaining the overall flatness of the disk. HMT's texturizing process, a highly automated patented
process, produces a controlled roughness on the disk's surface to improve its stiction characteristics. HMT currently utilizes
different texture processes, including laser texturing, to address different customer requirements. The wash process is developed to
present a clean disk surface to the sputter process. Subsequent processes occur in class ten clean rooms only.

Sputter, Dip Lube and Kiss Buff. The sputter process uses equipment and a process, similar to that used in
silicon wafer fabrication, in which layers of materials are deposited on the disk through a vacuum sputtering process. The chrome and
magnetic layers determine the magnetic properties of the disk. The carbon layer is a protective overcoat. After sputtering, a
microscopic layer of lubrication is applied to the disk's surface to improve durability and reduce surface friction. After
lubrication, a surface finishing step is applied, commonly referred to as kiss buff or tape burnish.

Glide/Certify. In the test and certification process, each finished disk is optically and electronically
screened and certified as acceptable based on the customer's specifications. A robotically controlled tester electronically tests for
glide performance. The tester then writes information onto the disk, reads it back and erases it, simulating performance in the
customer's disk drive. Each disk is tested for parametrics, errors in the read/erase process and surface defects.

The conversion of a specialized aluminum alloy blank into a final product requires two days.



Quality Assurance

HMT has a dedicated quality assurance group. We believe that our quality assurance program allows us to
realize superior product yields and consistently produce a quality product. Because a high quality product is critical to achieving
strong operating results and high customer satisfaction, HMT's emphasis on this area will remain a top priority. The organization
consists of four separate groups:

Application Engineering.Our Application Engineering group is responsible for reviewing customer
requirements and specifications by conducting specification reviews and soliciting customer and internal manufacturing feedback.
Other functions include correlating and evaluating the results of HMT and customer testing, generating standards and performing
source audits.

Supplier Quality Engineering.Because quality assurance is a critical aspect of our strategy, the
emphasis on quality must extend to the supplier level. Our Supplier Quality Engineering group is responsible for ensuring incoming
product quality through auditing suppliers, reviewing process data, establishing internal specifications and creating quality
procedures and practices. The group also establishes material specifications, supplier benchmarking and standards for qualification
of the supplier base.

Process Quality.Our Process Quality group is responsible for performing ongoing reliability testing,
process improvement testing and new product development testing. Specific functions involve statistical process control analysis,
gauge repeatability and reproducibility studies, equipment calibration, process qualification improvements and in-process quality
audits.

Customer Support.Our Customer Support group acts as liaison between the customer and our
manufacturing organization. All customer concerns and issues are handled through the group. Other responsibilities include corrective
action requests, non-conforming material reviews, return material authorizations and document control.

Manufacturing Facilities and Capacity

Our manufacturing facilities, distribution center and administrative offices are located in Fremont,
California. Our Fremont facility received ISO 9001 certification in May 1996. We currently operate 19 production scale sputtering
lines for production and development of products. A typical sputtering line consists of one sputtering machine and associated
equipment, such as texturizers, lubricators, glide testers and certifiers. Our facilities currently operate seven days a week, 24
hours per day.

In fiscal 1997, we completed construction of a new 124,000 square foot production facility at our Fremont,
California site. We brought four production scale sputtering lines into service during fiscal 1997, six in 1998, and an additional
two in fiscal 1999. This building has capacity for four more lines. During fiscal 1997, we also completed the first phase of
expansion of our facility in Eugene, Oregon, commencing volume production of aluminum substrates and nickel-plated and polished
substrates at that site. During the third quarter of fiscal 1999, we completed the second phase of expansion of the Eugene facility,
adding more polishing capacity. Also, during the third quarter of fiscal 1999, we idled seven sputtering lines and associated
equipment and facilities in connection with our restructuring plan.



Technology

We believe that there are a number of factors that are key to establishing and maintaining an advanced
technology position. We are optimizing precious metal alloys, based on a cobalt chromium platinum boron alloy, for future products
with coercivities that can support foreseeable demand for increased storage capacity. We also have extensive expertise in the
deposition of these and other alloys onto disks. We use state-of-the-art static sputtering machines in the development and production
of disks. Static machines differ from in-line, pallet machines used by some other disk manufacturers in a number of important
respects. Static sputtering machines process one stationary disk at a time, allowing for greater control of alloy deposition and
minimizing spatial and temperature variation; use isolated process chambers, permitting the manufacturer to control and optimize each
process step separately; and do not require a pallet, reducing the risk of contamination of the disk surface during processing. We
have further enhanced the performance of sputtering equipment supplied by vendors through internally developed, proprietary and
patented modifications.

We believe our unique tribology approach, which minimizes detrimental interaction between the head and disk, is
another area of strength. The method involves balancing the inter-relationship between texturizing, carbon overcoating and
lubrication. Our texturing process, a highly automated patented process, produces a controlled roughness on the disk's surface to
improve its stiction and defect characteristics. HMT currently utilizes different texture processes, including laser texturing to
address different customer requirements. This process provides increased protection where the head most often comes into contact with
the disk, while also minimizing the distance between the head and the disk magnetics in other regions of the disk where data is
stored and read. A nitrogen-containing carbon overcoat offers superior wear resistance. Application of our in-house blended lubricant
results in disks that can withstand an extreme range of temperature and humidity conditions. These additional layers must be thick
enough to achieve the desired protection of the disk and thin enough to minimize the distance between the head and the magnetic layer
of the disk. We believe that our application of these technologies, with particular attention to the inter-relationship between the
technologies and their combined effect on disk performance, have enabled us to develop competitive high-capacity disks.

We also devote considerable resources to developing disks for drives utilizing new head technology. Head
technology, traditionally based on flying inductive heads that combine the read and write function within one head, has gone through
significant evolution. Important technologies, such as GMR heads, have emerged. GMR head technology separates the read and write
function to different elements of the head. By physically disconnecting the writing and readback processes each can be individually
tuned for optimized performance. The GMR head, which has even higher sensitivity than MR heads, thereby producing more output, is the
head of the future. In order to take advantage of the technological potential of these new head technologies and enable us to play a
role in setting design specifications for the disk drive product, HMT works directly with head manufacturers to develop compatible
disks. We have demonstrated the ability to produce disks for the new head formats through the use of new alloy systems, modified
equipment and optimized processes.

We believe that our materials science expertise and ongoing commitment to developing new technologies is critical
to remaining competitive and achieving desired operating results. We expect our research and development efforts to remain focused on
alloy and process development, substrate finish and texture, overcoat development, and compatibility with advanced recording
concepts. As we have done in the past, we intend to conduct many of our development programs directly on production lines,
facilitating transition to high volume commercial production and minimizing development expense. During the fiscal years 1997, 1998,
1999 and 2000, we incurred $5.8 million, $8.8 million, $9.7 million and $9.1 million, respectively, of research and development
expenses. We believe that our future success depends on our ability to continue to enhance our existing products and to develop new
products.

Customers, Sales and Support

We sell our products directly to independent OEM disk drive manufacturers for incorporation primarily into
hard disk drives which are marketed under the manufacturers' own labels. The following table sets forth the percentage of net sales
attributable to sales to our principal customers in fiscal 2000, fiscal 1999 and fiscal 1998:

`Fiscal     Fiscal     Fiscal
                                      2000       1999       1998
                                    ---------  ---------  ---------
      Maxtor.......................     60.5%      36.0%      23.4%
      Samsung......................      7.5%      17.8%      16.0%
      Iomega.......................     14.6%      15.2%      28.9%
      Western Digital..............     13.3%      24.1%      19.0%`

Iomega utilizes the disks in its removable media hard disk drives. Our other customers during fiscal
1999 included SyQuest Technologies, Incorporated (Syquest). During the third quarter of fiscal 1999, SyQuest filed for protection
under Chapter 11 of the Bankruptcy Code. The Company's other customers during fiscal 1998 included Micropolis Corporation
(Micropolis) and Quantum Corporation ("Quantum"). During the third quarter of fiscal 1998, Micropolis filed for protection under
Chapter 11 of the Bankruptcy Code. Due to cessation of its high-end manufacturing operations, Quantum's high-end products are now
being manufactured by Matsushita Kotobuki Electronics Industries ("MKE"), and we shipped products to MKE during fiscal 1998. Due to
the rapid and frequent development of new disk drive products, it is common in the industry for the relative mix of customers and
products to change rapidly, even from quarter to quarter.

We have generally sold our products to customers pursuant to purchase orders and similar short-term arrangements.
In June 1996, we entered into a long-term supply agreement with Maxtor covering the supply of disks to Maxtor through June 2001. This
agreement is subject to a number of conditions and qualifications and there can be no assurance that Maxtor will in fact remain a
significant customer during the term of the agreement.

We believe that close technical collaboration with our customers and their other suppliers during the design phase
of new disk drives facilitates integration of our products into new disk drives, improves our ability to rapidly reach cost effective
high volume manufacturing and enhances the likelihood that we will become a primary supplier of thin-film disks for new disk drive
products. However, the design-in process is ongoing and recurs frequently, and we must compete for participation in each new product
program, even those of existing customers.

Our customer sales and service efforts are an integral part of maintaining strong customer relations. The sales
and service organization processes requests from customers concerning product needs and acts to mobilize our resources to fulfill
customer requests.

Although HMT has broadened its customer base, there are a relatively small number of disk drive manufacturers, and
we expect that our dependence on a few customers will continue in the future. Additionally, there is the possibility that one or more
of our customers could develop or expand their ability to produce thin-film disks internally and, as a result, could reduce the level
of purchases or cease purchasing from us or could sell thin-film disks in competition with us. For example, MMC Technology,
Incorporated (MMC Technology), a division of Hyundai Electronics America, and an affiliate of Maxtor, began internal media production
of thin-film disks during fiscal 1998. There has also been a trend toward consolidation in the disk drive industry that we expect to
continue. For example, during fiscal 1998, StorMedia, one of our competitors, acquired another of our competitors; Akashic Memories
Corporation ("Akashic"), a subsidiary of Kubota, Inc.. Then, during fiscal 1999, Stormedia filed for protection under Chapter 11 of
The Bankruptcy Code. Also during fiscal 1999 one of our customers, Western Digital, announced it had sold all of its media
manufacturing operations to Komag Incorporated. Western Digital also signed a long term volume purchase agreement with Komag in
connection with the sale of its media manufacturing operations. Recently Hyundai Electronics America's announced the intended sale of
MMC Technology to Trace Corporation. In April 2000, we entered into a definitive merger agreement with Komag, Incorporated.
Under the terms of the definitive merger agreement, each issued and outstanding share of HMT stock will be converted into 0.9094
shares of Komag's common stock. This agreement is publicly available and we urge you to read it for further information. The merger
will be accounted for under purchase accounting and is subject to customary closing conditions, including regulatory approvals, the
approval of both companies' shareholders and both companies' lenders. The merger is expected to close in the third quarter of
calendar 2000. If any of our customers or competitors were to further combine and rationalize suppliers and competitive product
lines, our business, results of operations and financial condition could be materially adversely affected.





Backlog

Our sales are generally made pursuant to purchase orders that are subject to cancellation, modification,
quantity reductions or rescheduling without significant penalties. Customers typically provide us with forecasts of expected
requirements for the next three to six months and submit purchase orders 60 to 90 days in advance of shipment dates. Because these
purchase orders may be modified or rescheduled by customers on short notice and without penalty, we do not believe that our backlog
as of any particular date should be considered indicative of sales for any future period.

Competition

Competitors in the thin-film disk industry fall into three groups: U.S. non-captive manufacturers, Asian-based
manufacturers and U.S. captive manufacturers. Historically each of these groups has supplied approximately one-third of the worldwide
thin-film disk unit output. Our primary U.S. non-captive competitor is Komag, Incorporated. Asian-based competitors include Fuji
Electric Company Limited, Mitsubishi Kasei Corporation, Trace Corporation, Showa Denko K.K. and Hoya Corporation. As previously
noted, on April 26 we signed an agreement to merge with Komag. The merger is expected to close in the third quarter of calendar 2000.
Certain of these companies have significantly greater financial, technical and marketing resources than us. In addition, U.S. captive
manufacturers, which include certain computer manufacturers, as well as disk drive manufacturers such as Seagate Technology, Inc.
("Seagate") and MMC Technology, an affiliate of Maxtor, manufacture disks for their internal use as part of their vertical
integration programs. These companies could increase their internal production and reduce or cease purchasing from independent disk
suppliers such as the Company. In the event of an oversupply of disks, these customers are likely to utilize their internal capacity
prior to purchasing disks from independent manufacturers such as us. Moreover, while captive manufacturers have, to date, sold only
nominal quantities of thin-film disks in the open market, there can be no assurance that such companies will not in the future do so
in direct competition with us. Furthermore, there can be no assurance that other current and potential customers will not acquire or
develop capacity to produce thin-film disks for internal use, or that disk manufacturing capacity will not exceed demand. Any such
changes could have a material adverse effect on our business, operating results and financial condition. Announcement or
implementation of any of the following by our competitors could have a material adverse effect on our business, operating results and
financial condition: changes in pricing, product introductions, increases in production capacity, changes in product mix and
technological innovation.

The market for thin-film disk products is highly competitive, and we expect competition to increase in the future.
We believe that the principal competitive factors affecting this market include performance, quality, delivery capability and price.
We believe that our products compete favorably in the high-end segment of the market that we serve, especially with respect to
performance and quality. The thin-film disk industry is characterized by short product life cycles, ranging from nine to 12 months.
As a result, we must continually anticipate, and adapt our products to meet demand for increased storage capacity. There can be no
assurance that in the future we will be able to manufacture products on a timely basis with the quality and features necessary in
order to remain competitive. In addition, the development of technologically innovative products requires substantial investments in
research and development. Specifically, the thin-film disk industry is characterized by intense price competition. We have
experienced significant pricing pressures since fiscal 1998, and there can be no assurance that we will not face similar pressure in
fiscal 2001. Price competition has had and may continue to have a material adverse effect on our business, operating results and
financial condition.

Intellectual Property and Proprietary Rights

Although we attempt to protect our intellectual property rights through patents, copyrights, trade secrets and
other measures, we believe that our success will depend more upon the innovation, technological expertise and marketing abilities of
our employees. There can be no assurance that we will be able to protect our technology adequately or that competitors will not be
able to develop similar technology independently. We have 51 patents and six pending patent applications in the United States. In
addition, we have nine foreign patents. Patents may not be issued with respect to our pending patent applications, and our issued
patents may not be sufficiently broad to protect our technology. No assurance can be given that any patent issued to us will not be
challenged, invalidated or circumvented or that the rights granted thereunder will provide adequate protection to our products. In
addition, we have only limited patent rights outside the United States, and the laws of certain foreign countries may not protect our
intellectual property rights to the same extent as do the laws of the United States.

We may from time to time be notified by third parties that we may be infringing patents owned by such third
parties. If necessary, we may have to seek a license under such patents or modify our products and processes in order to avoid
infringement of such patents. There can be no assurance that such a license would be available on acceptable terms, if at all, or
that we could so avoid infringement of such patents, in which case our business, operating results and financial condition could be
materially adversely affected.

Litigation may be necessary to enforce our patents, copyrights or other intellectual property rights, to protect
our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of
infringement or claims for indemnification resulting from infringement claims by third parties. Such litigation, even if successful,
could result in substantial costs and diversion of resources and could have a material adverse effect on our business, operating
results and financial condition. See "Risk Factors - Intellectual Property and Proprietary Rights."

Sources of Supply

We rely on a limited number of suppliers for many materials used in our manufacturing processes, including
substrates, plating chemicals, abrasive tapes and slurries, certifier heads, sputter targets and certain other materials. In general,
we seek to have two or three suppliers for our requirements; however, there can be no assurance that we can secure more than one
source for all of our materials requirements in the future or that our suppliers will be able to meet our requirements on a timely
basis or on acceptable terms. Shortages have occurred in the past, and there can be no assurance that shortages will not occur in the
future, or that materials will not be available only with longer lead times. Moreover, changing suppliers for certain materials, such
as lube or buffing tape, may require that the product be requalified with each customer. Requalification could prevent an early
design, or could prevent or delay continued participation in disk drive programs for which our products have been qualified. In
addition, long lead times are required to obtain many materials. Regardless of whether these materials are available from established
or new sources of supply, these lead times could impede our ability to quickly respond to changes in demand and product requirements.
Furthermore, a significant increase in the price of one or more of these materials could adversely affect our business, operating
results and financial condition. While we have implemented procedures to monitor the quality of the materials received from our
suppliers, there can be no assurance that the materials will meet the Company's specifications and will not adversely impact
manufacturing yields or cause other production problems. In addition, there are only a limited number of providers for thin-film disk
manufacturing equipment, such as sputtering machines, glide testers and certifiers, and ordering additional equipment for replacement
or expansion requires long lead times, limiting the rate and flexibility of capacity expansion. Any limitations on, or delays in, the
supply of materials or equipment could disrupt our production volume and could have a material adverse effect on our business,
operating results and financial condition.

Environmental Regulation

Our operations and manufacturing processes are subject to certain environmental laws and regulations, which
govern our use, handling, storage, transportation, disposal, emission and discharge of hazardous materials and wastes, the pre-
treatment and discharge of process waste waters and the emission of air pollutants. We have from time to time been notified of minor
violations of environmental laws and regulations. These violations have been corrected in all material respects without undue
expense..Environmental laws and regulations, however, may become more
stringent over time, and there can be no assurance that our failure to comply with either present or future laws or regulations,
which may become more stringent, would not subject us to significant compliance expenses, production suspension or delay,
restrictions on expansion or the acquisition of costly equipment.

Employees

As of March 31, 2000, we had 1,445 full-time employees, with 1,249 in manufacturing, 71 in research and
development, 84 in quality assurance and 41 in administration and marketing. We believe we generally have good relations with our
employees. None of our employees are represented by a labor union, and we have never experienced a work stoppage. We believe that
attracting and motivating skilled technical personnel is vital to our success. Although competition for such personnel is intense, we
believe that we have not historically experienced difficulties in attracting personnel that are significantly different from those
experienced by our competitors.

Recapitalization Transaction

On November 30, 1995, we effected a leveraged recapitalization. The leveraged recapitalization and related
transactions consisted of: (i) our repurchase by from Hitachi Metals of shares of Common Stock representing all the outstanding
capital stock of HMT for an aggregate purchase price of $52.1 million in cash; (ii) the recapitalization of HMT through the issuance
of 21,968,057 shares of common stock for an aggregate purchase price of approximately $0.7 million, 5,900,000 shares of Series A
preferred stock for an aggregate purchase price of approximately $59.0 million, $47.0 million of subordinated promissory notes and
$60.0 million in senior debt with associated warrants to purchase 701,344 shares of common stock at an exercise price of $0.0003 per
share and (iii) the grant of options to purchase 11,451,865 shares of common stock under the 1995 Management Stock Option Plan and
1995 Stock Option Plan. The purchasers of HMT securities in the leveraged recapitalization included certain investment funds
affiliated with Summit Partners, L.P. and certain other investment funds, our management and employees and Hitachi Metals. The terms
of the leveraged recapitalization were determined through negotiations between Hitachi Metals and Summit Partners, who, prior to the
leveraged recapitalization, did not have any affiliation with HMT. Pursuant to these negotiations, the shares of common stock were
valued at $0.03 per share, the shares of Series A preferred stock were valued at $10.00 per share, and the subordinated notes were
valued at face value. The values of these securities were confirmed by a third party appraisal.

The leveraged recapitalization has been accounted for as a recapitalization, and accordingly, no change in the
accounting basis of our assets has been made.

As of November 30, 1995 (immediately prior to the leveraged recapitalization), we had $98.5 million in assets and
$122.7 million in liabilities. Immediately following the leveraged recapitalization, we had $110.9 million in assets, $132.1 million
in liabilities (including a $60.0 million senior bank term loan and $47.0 million of subordinated notes) and $59.0 million of Series
A preferred stock.

In April 2000, HMT entered into a definitive merger agreement with Komag, Incorporated. Under the terms of the
definitive merger agreement, each issued and outstanding share of HMT stock will be converted into 0.9094 shares of Komag's common
stock. The merger will be accounted for under purchase accounting and is subject to customary closing conditions, including
regulatory approvals, the approval of both companies' shareholders and lenders. The merger is expected to close in the third quarter
of calendar 2000.





RISK FACTORS

In addition to the other information in this Annual Report on Form 10-K, the following risk factors should
be considered carefully in evaluating HMT and our business. This Annual Report on Form 10-K contains forward-looking statements which
involve risks and uncertainties. Our actual results may differ significantly from the results discussed in the forward-looking
statements. Factors that might cause such a difference include, but are not limited to, those discussed below.

Fluctuations in Operating Results

Our operating results historically have been, and may continue to be, subject to significant quarterly and
annual fluctuations. As a result, our operating results in any quarter may not be indicative of our future performance. Factors
affecting operating results include: market acceptance of new products; timing of significant orders; changes in pricing by us or our
competitors; timing of product announcements and product transitions by us, our customers or our competitors; order cancellations,
modifications and quantity adjustments and shipment reschedulings; changes in product mix; manufacturing yields; the level of
utilization of our production capacity; increases in production and engineering costs associated with initial manufacture of new
products; and changes in the cost of, or limitations on, the availability of materials. The impact of these and other factors on our
revenues and operating results in any future period cannot be forecasted with certainty. Our expense levels are based, in part, on
our expectations as to future revenues. Because our sales are generally made pursuant to purchase orders that are subject to
cancellation, modification, quantity reduction or rescheduling on short notice and without significant penalties, our backlog as of
any particular date may not be indicative of sales for any future period, and such changes could cause our net sales to fall below
expected levels. If revenue levels are below expectations, operating results are likely to be materially adversely affected. Net
income, if any, and gross margins may be disproportionately affected by a reduction in net sales because a proportionately smaller
amount of our expenses varies with our revenues.

We derive substantially all of our net sales from the sale of thin-film disks to a small number of customers. We
typically supply disks in volume for a limited number of disk drive products at any one time (14 as of March 31, 2000), and these
products have an extremely short life cycle. Due to the rapid technological change and frequent development of new disk drive
products, it is common in the industry for the relative mix of customers and products to change rapidly, even from quarter to
quarter. Generally, new products have higher average selling prices than more mature products. Therefore, our ability to introduce
new products in a timely fashion is an important factor in its continued success. Moreover, manufacturing yields and production
capacity utilization impact our operating results. New products often have lower manufacturing yields and are produced in lower
quantities than more mature products. If production for a disproportionate number of new products is commenced in a given quarter or
if manufacturing yields for such products do not improve in a timely manner, our operating results for such quarter could be
adversely affected. For example, during the quarter ended March 31, 1997, our operating results were adversely affected due partly to
lower yields associated with initial production of a significant number of new products. Manufacturing yields generally improve as
the product matures and production volumes increase. Manufacturing yields also vary depending on the complexity and uniqueness of
product specifications. The ability to adjust manufacturing procedures to reduce costs and improve manufacturing yields and
productivity during a product's life is limited, and many adjustments can only be implemented in connection with new product
introductions or upgrades. Small variations in manufacturing yields and productivity can have a significant impact on operating
results. Furthermore, because the thin-film disk industry is capital intensive and requires a high level of fixed costs, operating
results are also extremely sensitive to changes in volume. Substantial advance planning and commitment of financial and other
resources is necessary for expansion of manufacturing capacity, while our sales are generally made pursuant to purchase orders that
are subject to cancellation, modification, quantity reduction or rescheduling without significant penalties. The impact of any of the
foregoing factors could have a material adverse effect on our business, operating results and financial condition.

Dependence on a Limited Number of Customers; Lengthy Sales Cycle

During fiscal 2000, we shipped most of our thin-film disks to four customers: Iomega, Maxtor, Western Digital,
and Samsung. Aggregate shipments to Iomega, Maxtor, Western Digital and Samsung represented 14.6%, 59.8%, 12.6% and 8.3%,
respectively, of net sales in fiscal 2000.There are a relatively small
number of disk drive manufacturers, and we expect that our dependence on a few customers will continue in the future. Loss of, or a
reduction in, orders from one or more of our customers could result in a substantial reduction in net sales and operating results.
During fiscal 1997, one of our customers, Micropolis, filed for protection under Chapter 11 of The Bankruptcy Code. During fiscal
1998, SyQuest, another of our customers, filed for protection under Chapter 11 of The Bankruptcy Code. Because many of our expense
levels are based, in part, on our expectations as to future revenues, decreases in net sales may result in a disproportionately
greater negative impact on operating results. Our success will therefore depend on the success of our key customers. One or more of
our customers could develop or expand their ability to produce thin-film disks internally and, as a result, could reduce the level of
purchases or cease purchasing from us or could sell thin-film disks in competition with us. For example, MMC Technology, an affiliate
of Maxtor, manufactures thin-film disks for Maxtor's use. Also during 1999 one of our customers, Western Digital, announced it had
sold all of its media manufacturing operations to our largest U.S. competitor, Komag. Western Digital also signed a long-term volume
purchase agreement with Komag in connection with the sale of its media manufacturing operations. During calendar 2000, Trace
Corporation announced a pending purchase of MMC Technology and Komag and HMT announced a pending merger. There has also been a trend
toward consolidation in the disk drive industry, which we expect to continue. For example, in February 1996, two leading disk drive
manufacturers, Seagate and Conner Peripherals, Inc., combined to form the world's largest disk drive manufacturing company. In
addition, during fiscal 1996, Hewlett-Packard Co. exited the disk drive business. If any of the Company's customers or competitors
were to further combine and reduce suppliers and competitive product lines, our business, operating results and financial condition
could be materially adversely affected.

We have generally sold our products to customers pursuant to purchase orders and similar short-term arrangements.
In June 1996, we entered into a long-term supply agreement with Maxtor covering the supply of disks to Maxtor through June 2001. This
agreement is subject to a number of conditions and qualifications, and there can be no assurance that Maxtor will in fact remain a
significant customer during the term of the agreement.

Qualifying thin-film disks for incorporation into a new disk drive product requires us to work extensively with
the customer and the customer's other suppliers to meet product specifications. Therefore, customers often require a significant
number of product presentations and demonstrations, as well as substantial interaction with our senior management, before making a
purchasing decision. Accordingly, our products typically have a lengthy sales cycle, which can range from six to 12 months, during
which we may expend substantial financial resources and management time and effort with no assurance that a sale will result.

Dependence on Intensely Competitive and Cyclical Hard Disk Drive Industry

Our operating results are dependent on current and anticipated demand for high-end, high-capacity hard disk
drives, which in turn depend on the demand for high-end PCs, network servers and workstations. The disk drive industry is cyclical
and historically has experienced periods of oversupply and reduced production levels, resulting in significantly reduced demand for
thin-film disks, as well as pricing pressures. The effect of these cycles on suppliers, including thin-film disk manufacturers, has
been magnified by hard disk drive manufacturers' practice of ordering components, including thin-film disks, in excess of their needs
during periods of rapid growth, which increases the severity of the drop in the demand for components during periods of reduced
growth or contraction.During fiscal 1999, the disk drive industry
experienced a significant decline in demand.There can be no assurance that
current levels of demand will not decline, or that future demand will be sufficient to support existing and future capacity. A
decline in demand for hard disk drives would have a material adverse effect on our business, operating results and financial
condition. Additionally, the hard disk drive industry is intensely competitive, and, in the past, some disk drive manufacturers have
experienced substantial financial difficulties. For example, during 1997, one of the Company's customers, Micropolis, filed for
protection under Chapter 11 of the Bankruptcy Code. Then, during fiscal 1998, SyQuest, another of the Company's customers, filed for
protection under Chapter 11 of the Bankruptcy Code.There can be no assurance
that we will not face greater difficulty in collecting receivables or be required to offer more liberal payment terms in the future,
particularly in a period of reduced demand. Any failure to collect or delay in collecting receivables could have a material adverse
effect on our business, operating results and financial condition.

Expansion of Capacity

While the industry is currently suffering from excess capacity, a rebound in demand could require us to resume
our capacity expansion. During fiscal 1998 and 1997 we were operating at close to full capacity.In fiscal 1997, we completed
construction of a new 124,000 square foot production facility at our Fremont, California site. We brought four production scale
sputtering lines into service during fiscal 1997, six in 1998, and an additional two in fiscal 1999. This building has capacity for
four more lines. During fiscal 1997, we completed the first phase of expansion of our facility in Eugene, Oregon, commencing volume
production of aluminum substrates and nickel-plated and polished substrates at that site. During the third quarter of fiscal 1999, we
completed the second phase of expansion of the Eugene facility, adding more polishing capacity. During the third quarter of fiscal
1999, we idled seven sputtering lines and associated equipment and facilities in connection with our restructuring plan.

We currently expect to spend approximately $10 million over the next 12 months for maintenance and upgrades to
production equipment, a substantial majority of which will be spent on our Fremont, California facility.

Intense Competition

The market for our products is highly competitive, and we expect competition to continue in the future. There
can be no assurance that in the future we will be able to develop and manufacture products on a timely basis with the quality and
features necessary in order to remain competitive. Competitors in the thin-film disk industry fall into three groups: U.S. non-
captive manufacturers, Asian-based manufacturers and U.S. captive manufacturers. Historically, each of these groups has supplied
approximately one-third of the worldwide thin-film disk unit output. Our primary U.S. non-captive competitor is Komag. Asian-based
competitors include Fuji, Mitsubishi, Trace Corporation, Showa Denko and Hoya. In addition, U.S. captive manufacturers, which include
certain computer manufacturers, as well as disk drive manufacturers such as Seagate and MMC Technology, an affiliate of Maxtor,
manufacture disks for their internal use as part of their vertical integration programs. During periods of industry excess capacity,
such as was experienced during fiscal 1999 and 2000, these customers favor their internal capacity over purchasing disks from
independent suppliers such as us. Moreover, while captive manufacturers have, to date, sold only nominal quantities of thin-film
disks in the open market, there can be no assurance that such companies will not in the future do so in direct competition with us.
These companies could increase their internal production and reduce or cease purchasing from independent disk suppliers such as us.
Also, consolidation of customers and competitors could reduce demand for our products. For example, during fiscal 1999, Komag
purchased Western Digital's U.S. media manufacturing operations and Western Digital signed a long-term volume purchase agreement in
connection with the sale. During calendar 2000, Trace Corporation announced a pending purchase of MMC Technology and Komag and HMT
Technology Corporation announced a pending merger.

Furthermore, there can be no assurance that other current and potential customers will not acquire or develop
capacity to produce thin-film disks for internal use. Any such changes could have a material adverse effect on our business,
operating results and financial condition. Announcement or implementation of any of the following by our competitors could have a
material adverse effect on our business, operating results and financial condition: changes in pricing, product introductions,
increases in production capacity, changes in product mix and technological innovation. Specifically, the thin-film disk industry is
characterized by intense price competition. We experienced significant pricing pressure during fiscal 1998, 1999 and 2000, and there
can be no assurance that we will not experience increased price competition in the future. Pricing pressure has included, and may in
the future include, demands for discounts, long-term supply commitments, just-in-time inventory warehouses and extended payment
terms. Any increase in price competition could have a material adverse effect on our business, operating results and financial
condition.

During fiscal 1999 and 2000, many of our competitors and customers had excess disk manufacturing capacity,
resulting in industry capacity in excess of levels of demand. As a result, we and many of our customers and competitors have
experienced poor operating results. During fiscal 1999 and 2000, we recorded a net loss of $21.0 million and $51.6 million
respectively, primarily a result of declining demand and increased competition.

These increased levels of competition, could have further material adverse effects on our business, operating
results and financial condition.

Rapid Technological Change

Rapid technological development and short product life cycles have characterized the thin-film disk industry.
Product life cycles typically range from nine to 12 months. As a result, we must continually anticipate, and adapt our products to
meet, demand for increased storage capacity. Although we are continually developing new products and production techniques, there can
be no assurance that we will be able to anticipate technological advances in disk drives and develop products incorporating such
advances in a timely manner or to compete effectively against our competitors' new products. In addition, there can be no assurance
that customers will certify our products for inclusion in new disk drive products. We anticipate continued changes in the
requirements of the disk drive industry and thin-film disk manufacturing technologies, and there can be no assurance that the future
technological innovations will not reduce demand for thin-film disks. Our business, operating results and financial condition will be
materially adversely affected if our efforts are not successful, if the technologies that we have chosen not to develop prove to be
competitive alternatives or if any trend develops toward technology that would replace thin-film disks as a storage medium.

Dependence on Suppliers

We rely on a limited number of suppliers for many materials used in its manufacturing processes, including
aluminum blanks, substrates, sputter targets, plating chemicals, abrasive tapes and slurries, certifier heads and certain other
materials. In general, we seek to have two or three suppliers for its requirements; however, there can be no assurance that we can
secure more than one source for all of our materials requirements in the future or that our suppliers will be able to meet our
requirements on a timely basis or on acceptable terms. Shortages have occurred in the past and there can be no assurance that
shortages will not occur in the future, or that materials will be available without longer lead times. Moreover, changing suppliers
for certain materials, such as lube or buffing tape, may require that the product be requalified with each customer. Requalification
could prevent an early design-in, or could prevent or delay continued participation in disk drive programs for which our products
have been qualified. In addition, long lead times are required to obtain many materials. Regardless of whether these materials are
available from established or new sources of supply, these lead times could impede our ability to quickly respond to changes in
demand and product requirements. Furthermore, a significant increase in the price of one or more of these materials could adversely
affect our business, operating results and financial condition. In addition, there are only a limited number of providers for thin-
film disk manufacturing equipment, such as sputtering machines, glide testers and certifiers, and ordering additional equipment for
replacement or expansion requires long lead times, limiting the rate and flexibility of capacity expansion. Any limitations on, or
delays in, the supply of materials or equipment could disrupt our production volume and could have a material adverse effect on our
business, operating results and financial condition.

Process Quality Control Risks

The manufacture of our high-performance thin-film disks requires a tightly controlled multi-stage process and
the use of high-quality materials. Efficient production of our products requires utilization of advanced manufacturing techniques and
clean room facilities. Disk fabrication occurs in a highly controlled, clean environment to minimize dust and other yield- and
quality-limiting contaminants. Despite stringent manufacturing controls, weaknesses in process control or minute impurities in
materials may cause a substantial percentage of the disks in a lot to be defective. The success of our manufacturing operation
depends in part on our ability to maintain process control and minimize such impurities in order to maximize our yield of acceptable
high-quality disks. Minor variations from our specifications could have a disproportionately adverse impact on manufacturing yields.
For example, in the quarter ended March 31, 1995, our operating results were materially adversely affected by chlorine contamination
of our thin-film disk products that we believe resulted from chlorine contamination of disk carriers provided by one of our
suppliers. While we have implemented procedures to monitor our manufacturing process and the quality of production materials, there
can be no assurance that such procedures will be adequate.

Need for Additional Financing

The disk media business is capital intensive, and we believe that in order to remain competitive, we may
require additional financing resources over the next several years for capital expenditures, working capital, and research and
development. Among other things, our customers prefer suppliers that can meet a substantial portion of their volume requirements, so
we will need to expand our manufacturing capacity to remain competitive.We
currently expect to spend approximately $10 million on capital expenditures principally directed towards the maintenance and upgrade
of production equipment over the next 12 months. We believe that existing cash balances, cash generated from operations, and funds
available under our credit facility will provide adequate cash to fund our operations for at least the next 12 months. Additional
sources of long-term liquidity could include cash generated from operations and debt and equity financings. If we were to resume a
facilities expansion, we could require additional capital.As of March 31,
2000, the Company had approximately $85.9 million in working capital, including approximately $55.3 million in cash and cash
equivalents.In addition, the Company's operations generated cash flow of
$4.6 million during the year ended March 31, 2000.

Intellectual Property and Proprietary Rights

Although we attempt to protect our intellectual property rights through patents, copyrights, trade secrets and
other measures, there can be no assurance that we will be able to protect our technology adequately or that competitors will not be
able to develop similar technology independently.We have 51 patents and nine
pending patent applications in the United States. In addition, we have nine foreign patents.Patents may not be issued with respect to our pending patent applications, and our issued patents may not be
sufficiently broad to protect our technology. No assurance can be given that any patent issued to us will not be challenged,
invalidated or circumvented or that the rights granted thereunder will provide adequate protection to our products. In addition, we
have only limited patent rights outside the United States, and the laws of certain foreign countries may not protect our intellectual
property rights to the same extent as do the laws of the United States.

We are from time to time notified by third parties that we may be infringing patents owned by such third parties.
If necessary, we may have to seek a license under such patents or modify our products and processes in order to avoid infringement of
such patents. There can be no assurance that such a license would be available on acceptable terms, if at all, or that we could so
avoid infringement of such patents, in which case our business, operating results and financial condition could be materially
adversely affected.

Litigation may be necessary to enforce our patents, copyrights or other intellectual property rights, to protect
our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of
infringement or claims for indemnification resulting from infringement claims by third parties. Such litigation, even if successful,
could result in substantial costs and diversion of resources and could have a material adverse effect on our business, operating
results and financial condition.

Dependence on Key Personnel

Our future operating results depend in significant part upon the continued contributions of our officers and
personnel, many of whom would be difficult to replace. We do not have employment agreements with any employee. The loss of our
officers or other key personnel, who are critical to our success, could have a material adverse effect on the business, operating
results and financial condition. In addition, our future operating results depend in part upon our ability to attract, train, retain
and motivate other qualified management, technical, manufacturing, sales and support personnel for our operations. Competition for
such personnel is intense, especially since many of our competitors are located near our facilities in Fremont, California. Among the
competitive factors in attracting personnel are compensation and benefits, equity incentives and geographic location. There can be no
assurance that we will be successful in attracting or retaining such personnel. The loss of the services of existing personnel as
well as the failure to recruit additional personnel could materially adversely effect our business, operating results and financial
condition.

Dependence on Fremont Manufacturing Facilities; Environmental Issues

Our Fremont facilities, which currently account for all of our finished products, are located near major
earthquake faults. Disruption of operations at any of our facilities for any reason, including power failures, work stoppages or
natural disasters such as fire, floods or earthquakes, would cause delays in, or an interruption of, production and shipment of
products, which could materially adversely affect our business, operating results and financial condition.

Our operations and manufacturing processes are subject to certain environmental laws and regulations, which govern
the Company's use, handling, storage, transportation, disposal, emission and discharge of hazardous materials and wastes, the pre-
treatment and discharge of process waste waters and its emission of air pollutants. We have from time to time been notified of minor
violations of environmental laws and regulations. These violations have been corrected in all material respects without undue
expense.Environmental laws and regulations, however, may become more
stringent over time, and there can be no assurance that our failure to comply with either present or future laws or regulations,
which may become more stringent, would not subject us to significant compliance expenses, production suspension or delay,
restrictions on expansion or the acquisition of costly equipment.



Risks of International Sales

In fiscal 2000, 1999 and 1998, substantially all of our net sales consisted of products delivered to customers
in Asia, primarily foreign subsidiaries of U.S. companies, and we anticipate that the substantial majority of our products will be
delivered to customers outside of the United States for the foreseeable future. Accordingly, our operating results are subject to the
risks of doing business in foreign jurisdictions, including compliance with, or changes in, the law and regulatory requirements of
foreign jurisdictions, local content rules, taxes, tariffs or other barriers, and transportation delays and other interruptions.
Although presently all of our sales are made in U.S. dollars, there can be no assurance that future international sales will not be
denominated in foreign currency.

Anti-Takeover Effects

Certain provisions of our Amended and Restated Certificate of Incorporation, and Bylaws and Delaware law,
including the provisions of Section 203 of the Delaware General Corporation Law, which restrict the ability of a substantial
stockholder to acquire us, may discourage certain transactions involving a change in control of HMT. In addition to the foregoing,
the ability of the Board of Directors to issue "blank check" preferred stock without further stockholder approval could have the
effect of delaying, deferring or preventing a change in control of HMT.

Risks of Intended Merger with Komag

In April 2000, the Company entered into a definitive merger agreement with Komag, Incorporated ("Komag").
Komag designs, develops, manufactures and markets high-performance thin-film disks. Under the terms of the definitive merger
agreement, each issued and outstanding share of HMT stock will be converted into 0.9094 shares of the Komag's common stock. The
merger will be accounted for under purchase accounting and is subject to customary closing conditions, including regulatory
approvals, the approval of both companies' shareholders and the Company's lenders. The merger is expected to close in the third
quarter of calendar 2000.

Investors and security holders are advised to read the joint proxy statement/prospectus regarding the business
transaction referenced in the foregoing information, when it becomes available, because it will contain important information. HMT
and Komag expect to mail a joint proxy statement/prospectus about the transaction to their respective stockholders. Such joint proxy
statement/prospectus will be filed with the Securities and Exchange Commission by both companies. Investors and security holders may
obtain a free copy of the joint proxy statement/prospectus (when available) and other documents filed by the companies at the
Securities and Exchange Commission's web site at http://www.sec.gov. The joint proxy statement/prospectus and such other documents
may also be obtained from HMT or Komag.

There are certain risks and uncertainties relating to the proposed merger with Komag which will be described in
the joint proxy statement/prospectus to be mailed to Komag and HMT's respective stockholders and will be filed with the Securities
and Exchange Commission.

Volatility of Convertible Note and Common Stock Prices

The trading price of our common stock could be subject to wide fluctuations in response to a variety of
factors, including quarterly variations in operating results, announcements of technological innovations or new products by us, our
customers or our competitors, developments in patents or other intellectual property rights, general conditions in the computer or
disk drive industry, comments made by analysts, including charges in analysts estimates and general economic and market conditions.
Additionally, the stock markets in general, and the market for technology stocks in particular, has experienced extreme price
volatility in recent years. This volatility has often had a substantial effect on the market prices of many technology companies for
reasons unrelated or disproportionate to the operating performance of such companies. Broad market fluctuations could have a
significant impact on the market price of the common stock.

Various factors such as changes in prevailing interest rates or changes in perceptions of our creditworthiness
could cause the market price of our 5 3/4% convertible subordinated notes due calendar 2004 to fluctuate significantly. The trading
price of the convertible notes could also be significantly affected by the market price of the common stock, which could be subject
to wide fluctuations in response to a variety of factors as discussed above.

Item 2. Properties

We own one 57,776 square foot building, used for manufacturing and administration, on approximately 4.3
acres of land in Fremont, California and another 124,000 square foot manufacturing and administrative facility on an adjacent five
acre parcel. We lease an adjacent 50,400 square foot building used primarily for manufacturing under a lease that expires in December
2003 with three five-year extension options. We also lease a nearby 60,312 square foot building used for administration, engineering
and distribution, under a lease that expires in May 2004.

We also own a 106,458 square foot building, used for manufacturing and administration, on approximately 4.6 acres
in Eugene, Oregon. We lease a nearby 23,970 square foot building used for engineering and distribution, under a lease that expires in
December, 2002, with two five-year extension options.

Our Fremont facilities, which currently account for all of our finished disk production, are located near major
earthquake faults. Disruption of operations for any reason, including power failures, work stoppages or natural disasters such as
fire, floods or earthquakes, could materially adversely affect our business, operating results and financial condition.

In April 2000, we entered into a definitive merger agreement with Komag, Incorporated. Komag designs,
develops, manufactures and markets high-performance thin-film disks. Under the terms of the definitive merger agreement, each issued
and outstanding share of HMT stock will be converted into 0.9094 shares of Komag's common stock. The merger will be accounted for
under purchase accounting and is subject to customary closing conditions, including regulatory approvals, the approval of both
companies' shareholders and lenders. The merger is expected to close in the third quarter of calendar 2000.



Item 7. Management's Discussion and Analysis of Financial Condition and Results of
Operations

The following discussion of our financial condition and results of operations should be read in conjunction
with our consolidated financial statements and notes thereto included elsewhere in this Annual Report on Form 10-K. This Management's
Discussion and Analysis of Financial Condition and Results of Operations and other parts of this Annual Report on Form 10-K contain
forward-looking statements that involve risks and uncertainties. Our actual results may differ significantly from the results
discussed in the forward-looking statements. Factors that might cause such a difference include, but are not limited to, those
discussed in Item 1 under the heading entitled "Risk Factors."

Overview

HMT Technology Corporation is an independent supplier of high-performance thin-film disks for high-end, high-
capacity hard disk drives, which in turn are used in high-end PCs, network servers and workstations. HMT was incorporated in December
1988 as a subsidiary of Hitachi Metals for the purpose of acquiring certain assets and certain liabilities of the thin-film division
of Xidex Corporation, which had been producing thin-film disks since calendar 1983. Since completing the Xidex acquisition, we have
continued to supply thin-film disks to manufacturers of hard disk drives. On November 30, 1995, we effected the leveraged
recapitalization pursuant to which we repurchased from Hitachi Metals, then the sole stockholder of HMT, all of the outstanding
shares of common stock of HMT, and certain investment funds, members of management and Hitachi Metals, purchased common stock,
mandatorily redeemable Series A preferred stock and subordinated promissory notes.

Beginning in fiscal 1995, HMT's management team, many of whom had joined us since February 1994, refocused the
strategy and operations. The new management concentrated on the 3 1/2-inch disk form factor, focused on the high-end, high-capacity
segment of the disk drive market and expanded the customer base. In addition, HMT implemented an extensive quality assurance program,
developed proprietary manufacturing processes and optimized production capacity utilization. These changes resulted in higher
production volumes, lower unit costs, and higher average selling prices primarily associated with new high-end products. As a result,
we increased sales and improved gross margins, achieving net income of $60.6 million for fiscal 1997 and $69.9 million for fiscal
1998, compared with a net loss of $8.9 million for fiscal 1995.

During March and April 1996, we sold 9,660,000 shares of common stock at $10.00 per share (including exercise of
the underwriters' over-allotment option) through our initial public offering. The net proceeds (after underwriter's discounts and
commissions and other costs associated with the initial public offering) totaled $88.7 million. In January 1997, we completed a $230
million private placement of the convertible notes to qualified institutional investors, resulting in net proceeds of approximately
$222.5 million (after offering costs). Proceeds from the issuance of the convertible notes were used to fully redeem the $59 million
of mandatorily redeemable Series A preferred stock and to prepay the $47 million principal balance of the subordinated promissory
notes issued pursuant to the leveraged recapitalization plus accrued interest and to fully repay $41 million in long-term borrowings
outstanding.

In fiscal 1997, we completed construction of a new 124,000 square foot production facility at our Fremont,
California site. We brought four production scale sputtering lines into service during fiscal 1997, six in fiscal 1998, and an
additional two in fiscal 1999. This building has capacity for four more lines. During fiscal 1997, we completed the first phase of
expansion of our facility in Eugene, Oregon, commencing volume production of aluminum substrates and nickel-plated and polished
substrates at that site.  During the third quarter of fiscal 1999, we
completed the second phase of expansion of the Eugene facility, adding more polishing capacity. During the third quarter of fiscal
1999, we idled seven sputtering lines and associated equipment and facilities in connection with our restructuring plan.



Pricing pressure was evident in calendar 1999; according to Trend Focus, worldwide shipments
of hard disk drives grew 20% to 174 million units in calendar 1999

According to Trend Focus, media unit shipments
grew 6.1% to 432 million in calendar 1999, with an estimated market value of
$3.4 billion, down 20% from 1998. Shipments from non-captive sources grew by approximately 4% while captive
manufacturer shipments grew by 7.5% over calendar 1998 levels as captive manufacturers favored increasing their capacity utilization
over making purchases from independent media suppliers.

Due to the changes in ownership resulting from our leveraged recapitalization, utilization of net operating losses
is limited to approximately $0.8 million per year over the loss carryforward period (expiring between 2008 and 2010). The benefit
from the net operating losses was recorded in the quarter ended December 31, 1995. Had we been obligated to pay taxes at the
statutory rates for fiscal 1996, net income would have been $30.7 million.

Fiscal Years Ended March 31, 2000, 1999 and 1998

Net Sales. Net sales were $192.8 million in fiscal 2000, $239.5 million in fiscal 1999 and $356.2
million in fiscal 1998. The decrease in net sales during fiscal 2000was a
result of a 1.1% decline in unit sales volume from fiscal 1999 to fiscal 2000 and a 18.6% decline in average selling prices over the
same period. The decline in both unit sales volume and average selling prices was generated by the continuing imbalance in supply and
demand for thin-film media during fiscal 2000.

The 32.8% decrease in net sales in fiscal 1999

Gross Profit.

Research and Development. Research and development expenses were $9.1 million, or 4.7% of net sales, in
fiscal 2000, $9.7 million, or 4.1% of net sales, in fiscal 1999 and $8.8 million, or 2.5% of net sales, in fiscal 1998. Research and
development expenses declined in absolute dollars in fiscal 2000 due primarily to decreased headcount after having

Selling, General and Administrative. Selling, general and administrative expenses were $9.8 million, or
5.1% of net sales, in fiscal 2000, $11.7 million or 4.8% of net sales, in fiscal 1999 and $13.7 million, or 3.9% of net sales, in
fiscal 1998.

Restructuring Charge. During the third quarter of fiscal 1999, we announced and implemented a restructuring
plan, which included a work force reduction of approximately 300 employees and the consolidation of our manufacturing operations. The
plan was primarily aimed at improving costs efficiencies by retiring older equipment and eliminating excess capacity. We recorded a
total charge of $15.7 million, which included a non-cash charge of $13.7 million for equipment and related spare parts taken out of
service during the quarter. The restructuring charge also included a charge of $1.8 million for severance costs, which were paid in
full during the third fiscal quarter, and a provision of $200,000 for contract services in connection with the restructuring plan.

Interest Expense, Net. Interest expense, net was $10.9 million, or 5.7% of net sales, in fiscal 2000, $11.0
million, or 4.6% of net sales, in fiscal 1999 and $8.2 million, or 2.3% of net sales, in fiscal 1998.

Provision for Income Taxes. We recorded an income tax benefit of $22.1 million in fiscal 2000, $9.0 million
in fiscal 1999 and an income tax provision of $30.0 million in fiscal 1998.

We have assessed the recoverability of deferred tax assets and, based on expectations about operating results for
the fiscal year ending March 31, 2000 and future years, determined it was more likely than not that the entire balance of deferred
tax assets would be recovered. Accordingly, we have not recorded a valuation allowance for deferred tax assets.



Liquidity and Capital Resources

During fiscal 2000 and fiscal 1999, we financed our cash requirements through cash from operating and
financing activities. Our operations provided net cash of $4.6 million, $68.3 million and $84.9 million for fiscal 2000, 1999 and
1998, respectively. Cash generated from operations during fiscal 2000 reflected a net loss of $51.6 million, offset by $56.1 million
in depreciation and amortization and $9.3 million provided by changes in operating assets and liabilities which were then reduced by
a $9.1 million change in deferred income taxes. Greater sales and operating margins contributed to the positive cash flow provided by
operations in fiscal 1998 and 1999.

Based on the $60.5 million cash position at December 31, 1999 and expected future cash flow, the Board of
Directors has authorized the Company to buy from time to time in open market purchases and negotiated private transactions, up to $30
million principal amount of the Company's 5 3/4% Convertible Subordinated Notes due 2004.

For fiscal 2000 and fiscal 1999, net cash used in investing activities was $5.0 million and $42.1 million,
respectively. We invested $6.0 million and $43.4 million in property, plant and equipment during fiscal 2000 and fiscal 1999,
respectively.

During fiscal 2000 and 1999, net cash from financing activities was $2.7 million and $1.8 million, respectively.
Cash provided by financing activities for fiscal 2000 reflects cash received for common stock issued in connection with our employee
stock purchase plan and the incentive stock option plans,as well as a $1.3
million tax benefit for disqualifying dispositions related to our incentive stock option plans.

Cash provided by financing activities for fiscal 1998 reflects the $13.4 million received for the common stock
issued in connection with our follow-on public offering, employee stock purchase plan, and the incentive stock option plans, as well
as a $2.0 million tax benefit for disqualifying dispositions related to our incentive stock option plans.

As of March 31, 2000, our principal sources of liquidity consisted of $55.3 million in cash and cash equivalents
and a $50.0 million revolving credit facility under which there were no borrowings.
Under the terms of the amended credit facility, any borrowings must be secured
by an equal amount of pledged cash and marketable securities.
At March 31,
2000, we had indebtedness of $230.0 million in convertible notes, that require semi-annual interest payments, which began July 15,
1997.We expect to spend approximately $10.0 million on capital expenditures
for the upgrade and maintenance of production equipment over the next twelve months.

We believe existing cash balances, cash generated from operations, and funds available under its credit facilities
will provide adequate cash to fund our operations for at least the next 12 months. Additional sources of long-term liquidity could
include cash generated from operations and debt and equity financings. We continue to have significant future obligations and expect
that we would require additional capital if we were to undertake a substantial expansion of manufacturing capacity. There can be no
assurance that we will be able to obtain alternative sources of financing on favorable terms, if at all, at such time or times as we
may require such capital.

Recent Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard No.
133 "Accounting for Derivative Instruments and Hedging Activities" (SFAS 133). SFAS 133 establishes accounting and reporting
standards for derivative instruments and for hedging activities. This statement becomes effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. In June 1999, the FASB issued Statement of Financial Accounting Standard No. 137 "Accounting for
Derivative Instruments - Deferral of the Effect Date of SFAS Statement No. 133" (SFAS 137). SFAS 137 defers the effective date of
SFAS 133 until June 15, 2000. We will adopt SFAS 133 in 2001. We expects the adoption of SFAS 133 will not affect results of
operations.

In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin No.
101 (SAB 101), "Revenue Recognition in Financial Statements". SAB 101 provides guidance for revenue recognition under certain
circumstances. We do not believe SAB 101 will have a material impact on the financial statements.

In March 2000, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 44 "Accounting for
Certain Transactions Involving Stock Compensation - an interpretation of APB Opinion No. 25". This interpretation has provisions that
are effective on staggered dates, some of which began after December 15, 1998 and others that become effective after June 30,
2000

Year 2000 Compliance

Our internal Year 2000 identification, assessment, remediation and testing efforts, which began in October
1997 were completed in 1999. The cost of these programs to date is not material to the financial position and results of operations
of HMT. However, there can be no guarantee that new costs will not be incurred in the future. To date, we have experienced no
significant problems with our systems as a result of the Year 2000 issue but can give no assurance that such problems will not arise
in the future.

We have also worked with our customers and suppliers to address their Year 2000 compliance issues in a timely
manner. To date we have experienced no disruptions in our operations due to customer or supplier Year 2000 issues but can give no
assurance that such problems may not arise in the future.

We have developed a contingency plan for operation without our computer based manufacturing control systems.
However, there are scenarios for failure of suppliers or infrastructure for which no contingency exists.



Item 7A. Quantitative and Qualitative Disclosures About Market Risk

As of March 31, 2000 and 1999, our investment portfolio consisted of fixed income securities of $54.7
million and $52.6 million, respectively. These securities, like all fixed income instruments, are subject to interest rate risk and
will decline in value if market interest rates increase. If market interest rates were to increase immediately and uniformly by 10%
from levels as of March 31, 2000 and 1999, the decline in the fair value of the portfolio would not be material. Additionally, we
have the ability to hold our fixed income investments until maturity and, therefore, we would not expect to recognize such an adverse
impact in income or cash flows.

Item 11. Executive Compensation



Compensation of Directors

Non-employee directors are paid an $10,000 annual retainer fee, $1,500 per meeting for attendance at
meetings of the Board of Directors and $500 per meeting for attendance at meetings of any committee thereof. In the fiscal year ended
March 31, 2000, the total cash compensation paid to non-employee directors was $62,500. Directors are reimbursed for reasonable out-
of-pocket expenses incurred in connection with attendance at such meetings in accordance with Company policy.

Each non-employee director of the Company (other than employees or affiliates of Summit Partners) receives
stock options under the 1996 Non-Employee Directors' Stock Option Plan (the "Directors' Plan") as compensation for services of the
Board of Directors. Option grants under the Directors' Plan are automatic and non-discretionary. The Directors' Plan provides for the
grant of an option to purchase 10,000 shares of Common Stock to each person who is first elected as a non-employee director after the
plan's adoption date. Each director who continues to serve as a non-employee director is granted an additional option to purchase
2,000 shares of Common Stock on the anniversary of the date of his or her initial grant or annually commencing with the fourth
anniversary of the plan's adoption date. During the last fiscal year, 10,000 options to purchase shares of the Company's Common Stock
were granted under the Directors' Plan. As of March 31, 2000, no options had been exercised under the Directors' Plan.

The 1996 Equity Incentive Plan (the "Incentive Plan") provides for grants of incentive stock options to
employees (including officers and employee directors) and nonstatutory stock options, restricted stock purchase awards, stock bonuses
and stock appreciation rights to employees (including officers and employee directors). The Incentive Plan is administered by the
Compensation Committee, which determines recipients and types of awards to be granted, including the exercise price, number of shares
subject to the award and the exercisability thereof. Restricted stock purchase awards granted under the Incentive Plan may be granted
pursuant to a repurchase option in favor of the Company in accordance with a service vesting schedule determined by the Board. During
the last completed fiscal year, 1,313 employees and consultants received options to purchase 1,442,240 shares of the Company's Common
Stock. As of March 31, 2000, 30,615 options had been exercised under the Incentive Plan.

(1)	Generally 20% of the options became exercisable immediately upon grant and the remaining 80%
will vest semi-annually for the next 24 months. The term of each option granted is generally the earlier of (i) ten years or (ii) 30
days after termination of the employment of the holder.

(2)	Based on an aggregate of 1,442,240 options granted to employees, consultants and directors, including the
Named Executive Officers, of the Company during the fiscal year ended March 31, 2000.

(3)	The exercise price per share of each option was equal to the fair market value of the Common Stock on the
date of grant.

(4)	The potential realizable value is calculated based on the term of the option at its time of grant. It is
calculated by assuming that the stock price on the date of grant appreciates at the indicated annual rate, compounded annually for
the entire term of the option and that the option is exercised and sold on the last day of its term for the appreciated stock price.
All calculations are based on rounding the number of years remaining on the term of the option to the nearest whole number. No gain
to the option holder is possible unless the stock price increases over the option term. The 5% and 10% assumed rates of appreciation
are derived from the rules of the Securities and Exchange Commission and do not represent the Company's estimate or projection of the
future Common Stock price.

(1)	Based on the fair market value of $3.3125 per share at March 31, 2000; the named Executive
Officers had no unexercised in-the-money options.

Bonus Plan. The Company has a discretionary bonus program for certain designated key employees of
the Company, including all executive officers, pursuant to which such employees are paid cash bonuses based upon the attainment of
certain specified corporate goals for the year established by the Board of Directors. The amount of the cash bonus to which each such
employee is entitled is determined by the Board.

Profit Sharing Plan. In May 1996, the Board of Directors approved an incentive-based profit
sharing plan for employees of the Company, including all executive officers. Under this Plan, employees are paid cash bonuses on a
quarterly basis based upon the attainment of certain specified corporate goals determined by the Board of Directors.

Stock. In addition to cash compensation, the Company's executive officers are eligible to receive
stock options under the Company's Employee Stock Purchase Plan (the "Purchase Plan") and the Incentive Plan. Approximately 1,284 of
the Company's approximately 1,468 employees are eligible to participate in the Purchase Plan. The Purchase Plan is implemented by
offerings of rights to all eligible employees from time to time by the Board. Eligible employees enroll in the Purchase Plan by
delivering to the Company, prior to the date selected by the Board as the offering date for the offering, an agreement authorizing
payroll deductions of up to 15% of such employees' base total compensation during the purchase period. The purchase price per share
at which shares of Common Stock are sold in an offering under the Purchase Plan is the lower of (i) 85% of the fair market value of a
share of Common Stock on first day of the offering or (ii) 85% of the fair market value of a share of Common Stock on the specified
purchase date. An aggregate of 3,000,000 shares of Common Stock is reserved for issuance under the Purchase Plan. If rights granted
under the Purchase Plan expire, lapse or otherwise terminate without being exercised, the shares of Common Stock not purchased under
such rights again becomes available for issuance under the Purchase Plan. For a description of the Incentive Plan, see "Director
Compensation" above.

Employment and Severance Agreements

In January 1996, the Company adopted an Executive Severance Plan (the "Severance Plan") providing for certain
benefits to executive officers of the Company in the event an executive's employment is involuntary terminated without cause
(generally meaning without any misconduct on the executive's part) or that the executive voluntarily terminates employment with good
reason (generally meaning that the executive's responsibilities, title or compensation was materially reduced). Upon the occurrence
of such an event, the Severance Plan provides for salary continuation for a period no greater than one year. In addition, the
Severance Plan provides for continued health benefits coverage to the extent permitted by the Consolidated Omnibus Budget
Reconciliation Act of 1985 and the Company's group health policies.

Ronald L. Schauer, Chief Executive Officer and Chairman of the Board of HMT, is party to a severance agreement
with HMT pursuant to which, upon consummation of the merger with Komag (see Item 6, Subsequent Events), Mr. Schauer is entitled to
receive a bonus in the total amount of $1,187,500 to be paid in 60 equal monthly amounts beginning on the first day of the month
following consummation of the merger. In addition, upon the occurrence of certain events after consummation of the merger, Mr.
Schauer may be entitled to acceleration of his bonus amount and acceleration of his executive stock options to provide for up to an
additional 24 months of service credit toward the vesting of his stock options.

REPORT OF INDEPENDENT ACCOUNTANTS

To The Board of Directors and Stockholders HMT Technology Corporation

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of
operations, of changes in stockholders' equity and of cash flows presented fairly, in all material respects, the financial position
of HMT Technology Corporation and its subsidiaries at March 31, 2000 and 1999, and the results of their operations and their cash
flows for each of the three years in the period ended March 31, 2000, in conformity with accounting principles generally accepted in
the United States. These financial statements are the responsibility of the company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing
standards generally accepted in the United States which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Summary of Significant Accounting PoliciesBasis of Presentation
HMT Technology Corporation ("HMT" or the "Company") is an independent supplier of high-performance thin-film
disks for high-end, high-capacity and removable hard disk drives, which in turn are used in PCs, network servers and workstations.
HMT was incorporated in Delaware in 1988 as a subsidiary of Hitachi Metals, Ltd. ("Hitachi Metals") to acquire certain assets and
certain liabilities of the thin-film division of Xidex Corporation, which had been producing thin-film disks since 1983. Since
completing the acquisition, the Company has continued to supply thin-film disks to manufacturers of hard disk drives.
Basis of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, HMT
FSC Ltd. (incorporated on February 14, 1996). All significant intercompany accounts and transactions have been eliminated in
consolidation.
Fiscal Year
The Company uses a 52-week fiscal year ending on March 31 and thirteen- to fourteen-week quarters that end on
the Sunday closest to the calendar quarter end.
Recapitalization
On November 30, 1995, the Company effected a leveraged recapitalization (the "Leveraged Recapitalization")
pursuant to which the
Company repurchased from Hitachi Metals, then the sole stockholder of the Company, all of the outstanding shares
of Common Stock of the Company, and certain investment funds, members of management and Hitachi Metals purchased newly issued Common
Stock, Mandatorily Redeemable Series A Preferred Stock ("Series A Preferred Stock") and subordinated promissory notes ("Subordinated
Notes") of the Company. As of November 30, 1995 (immediately prior to the Leveraged Recapitalization), the Company had approximately
$98.5 million in assets (unaudited) and approximately $122.7 million in liabilities (unaudited). Immediately following the Leveraged
Recapitalization, the Company had $110.9 million in assets (unaudited), and $132.1 million in liabilities (unaudited) (including
$60.0 million of senior bank term loan and $47.0 million of Subordinated Notes to stockholders) and $59.0 million of Series A
Preferred Stock. The Leveraged Recapitalization has been accounted for as a recapitalization, and accordingly, no change in the
accounting basis of the Company's assets has been made in the accompanying financial statements. The amount of cash paid and
securities issued to the stockholders of the Company exceeded the Company's net assets on the date of the transaction and has been
recorded in the equity section as distributions in excess of net book value.Cash and Cash EquivalentsThe Company considers all highly liquid investments with an original maturity of three months or less from the
date of purchase and money market funds to be cash equivalents. The Company maintains deposits with several financial institutions in
the United States. Deposits in banks may exceed the amount of insurance provided on such deposits. The Company has not experienced
any losses on its deposits of cash and cash equivalents.InventoriesInventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out basis.
The Company's inventories include high-technology materials that may be specialized in nature or subject to rapid technological
obsolescence. While the Company has programs to minimize the required inventories on hand and considers technological obsolescence in
estimating reserves to reduce recorded amounts to market value, such estimates could change in the future.
Property, Plant and Equipment
Property, plant and equipment is recorded at cost. Depreciation and amortization is provided using the
straight-line method over estimated useful lives of ten to thirty-five years for the building and improvements; five to ten years or
the lease term, whichever is shorter, for leasehold improvements; and three to five years for the machinery, equipment and furniture
and fixtures. The Company's policy is to regularly review the carrying amount of specialized assets and to evaluate the remaining
life and recoverability of such equipment in light of current market conditions. Upon disposal, the assets and related accumulated
depreciation are removed from the Company's accounts, and resulting gains or losses are reflected in operations.
Other Assets
Other assets are comprised principally of debt issue costs, which are capitalized and amortized to interest
expense using the effective interest method over the term of the related debt.
Warranties
The Company's products are generally warrantied for a period of 60 days from customer receipt. Estimated
future costs of repair, replacement or customer accommodations are reflected in the accompanying financial statements.
Income Taxes
The Company accounts for income taxes in accordance with Statement of Financial Accounting Standards No. 109
("SFAS 109"), "Accounting for Income Taxes." Under SFAS 109, the liability method is used for accounting for income taxes. The
realization of deferred tax assets is based on historical tax positions and expectations about future taxable income.
Revenue Recognition
Revenue is generally recognized upon shipment of product to the customer.
Research and Development
Research and development expenditures are charged to operations as incurred.
Foreign Currency Accounting
Substantially all of the Company's sales are denominated in U.S. dollars. Foreign currency transactions during
the period are immaterial and are included in operations.


Concentration of RisksThree customers accounted for 89.5% and 74.2% of accounts
receivable at March 31, 2000 and 1999, respectively. Significant
customers accounted for the following percentages of net sales in
fiscal 2000, 1999 and 1998:Years Ended March 31,

  Western Digital Corporation..........       13.30%      24.1%      19.0%

The Company sells substantially all of its production to Asian subsidiaries of U.S. companies. The
Company performs ongoing credit evaluations of its customers. The Company does not require collateral for its receivables and
maintains an allowance for potential credit losses, which have been insignificant to date.
The Company's Fremont facilities currently account for all of its finished goods production. Disruption of
operations at either the Eugene or Fremont site could cause delays in, or an interruption of, production and shipment of products,
which could materially adversely affect the Company's business, operating results and financial condition.
The Company maintains its short-term investments at one financial institution. The Company has not experienced
material losses on any of its investments.
Income Per Common Share
Basic income per common share is computed by dividing net income available to common stockholders by the
weighted average number of common shares outstanding for the period. Diluted income per common share is computed giving effect to all
potentially dilutive common shares that were outstanding during the period
Fair Value of Financial Instruments
The carrying amounts of cash and cash equivalents, other receivables and accrued liabilities are a reasonable
estimate of their fair value due to their short-term nature. The carrying value of the Company's long-term debt is a reasonable
estimate of their fair value based on interest rates as of March 31, 2000 for issues with similar remaining maturities.The estimated fair value amounts of the Company's financial instruments have been determined
by the Company, using appropriate market information and valuation methodologies. Considerable judgment is required to develop the
estimates of fair value, thus, the estimates provided herein are not necessarily indicative of the amounts that could be realized in
a current market exchange.
The Company calculates the fair value of financial instruments and includes this additional information in the
notes to financial statements when the fair value is different than the book value of those financial instruments. When the fair
value is equal to the book value no additional disclosure is made. The Company uses quoted market prices whenever available to
calculate these fair values. When quoted market prices are not available, the Company uses standard pricing models for various types
of financial instruments which take into account the present value of estimated future cash flows. The effect of using different
market assumptions and/or estimation methodologies may be material to the estimated fair value amounts.
Use of Estimates
The preparation of financial statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
Restructuring charge
During the third quarter of year ended March 31, 1999, The Company implemented a restructuring plan, which
included a work force reduction of approximately 300 employees and the consolidation of the Company's manufacturing operations. The
Company recorded a total charge of $15.7 million, which included a non-cash charge of $13.7 million for equipment and related spare
parts taken out of service during the quarter. The restructuring charge also included a charge of $1.8million for severance costs,
which were paid in full during the third quarter, and a provision of $200,000 for contract services in connection with the
restructuring.Recent PronouncementsIn June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard
No. 133 "Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133"). SFAS 133 establishes accounting and reporting
standards for derivative instruments and for hedging activities. This statement becomes effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. In June 1999, the FASB issued Statement of Financial Accounting Standard No. 137 "Accounting for
Derivative Instruments - Deferral of the Effect Date of SFAS Statement No. 133" ("SFAS 137"). SFAS 137 defers the effective date of
SFAS 133 until June 15, 2000. The Company will adopt SFAS 133 in 2001. The Company expects the adoption of SFAS 133 will not affect
results of operations.
In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 101 ("SAB 101"),
"Revenue Recognition in Financial Statements". SAB 101 provides guidance for revenue recognition under certain circumstances.
TheCompany does not believe SAB 101 will have a material impact on the
financial statements.

In March 2000, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation
No. 44 "Accounting for Certain Transactions Involving Stock Compensation - an interpretation of APB Opinion No. 25". This
interpretation has provisions that are effective on staggered dates, some of which began after December 15, 1998 and others that
become effective after June 30, 2000

Reclassifications

Certain amounts in the consolidated financial statements have been reclassified to conform with the current
year's presentation. The reclassification has no impact on previously reported net income or stockholders' equity (deficit).

4. Obligations Under Capital Leases

As of March 31, 2000 there were no assets under capitalized lease obligations. Assets under capitalized lease
obligations as of March 31, 1999 consisted of machinery and equipment with a cost of $1.6 million and accumulated amortization of
$0.6 million. No payment was outstanding as of March 31, 2000.

5. Debt

On November 17, 1997, the Company amended and restated the revolving credit agreement originally entered into
in 1995 pursuant to the leveraged recapitalization. This unsecured $100 million revolving credit agreement was with a consortium of
banks and had an expiration date of November 17, 2000. On November 2, 1998, the Company terminated this credit agreement and entered
into a new $50 million credit agreement with two banks expiring November 2, 2000. Interest rates for loans under the agreement vary
with the loan type and the level of various published interest rates.
Under the terms of the amended credit facility, any borrowings must be secured
by an equal amount of pledged cash and marketable securities.

Issuance of 5 3/4% Convertible Subordinated Notes

In January 1997, the Company completed a $230 million private placement of the convertible notes to qualified
institutional investors, resulting in net proceeds of approximately $222.5 million (after offering costs). Proceeds from the issuance
of the convertible notes were used to repay the $47 million principal balance of the subordinated notes plus accrued interest to
redeem the $59 million of Series A preferred stock issued pursuant to the leveraged recapitalization, and to fully repay the $41
million in long-term borrowings outstanding.

The convertible notes have an interest rate of 5 3/4% payable semiannually at January 15 and July 15, are
convertible into shares of common stock of the Company at a conversion price of $23.75 per share, subject to adjustment in certain
events, and mature January, 2004. The convertible notes are not redeemable prior to January 19, 2000. Thereafter the Company may
redeem the convertible notes initially at 103.286% and at decreasing prices thereafter to 100% at maturity, in each case together
with accrued interest. As of March 31, 2000, the fair value of the convertible notes, which is determined based on quoted market
price, was $92.9 million.

6. Commitments and Contingencies

The Company leases equipment and office and manufacturing
facilities under operating lease agreements. Future minimum payments
under these noncancelable operating leases are as follows:

Rent expense was approximately $4.7 million $4.1 million, and
$1.0 million for the years ended March 31, 2000, 1999 and 1998
respectively.

Equipment and Facilities Purchase Commitments

As of March 31, 2000, the Company had commitments to purchase
$5.1 million and $3.1 million of equipment and facilities,
respectively.

Contingencies

Because of the nature of its activities, the company  is at times
subject to pending and threatened legal actions which  arise out of
the normal course of business.  In the opinion of  management, based
in part upon the advice of legal counsel, the disposition of all such
matters will not have a material effect on the consolidated financial
statements.


Severance Agreement
Ronald L. Schauer, Chief Executive Officer and Chairman of the Board of HMT, is party to a severance agreement
with HMT pursuant to which, upon consummation of the merger (see Note 13), Mr. Schauer is entitled to receive a bonus in the total
amount of $1,187,500 to be paid in 60 equal monthly amounts beginning on the first day of the month following consummation of the
merger. In addition, upon the occurrence of certain events after consummation of the merger, Mr. Schauer may be entitled to
acceleration of his bonus amount and acceleration of his executive stock options to provide for up to an additional 24 months of
service credit toward the vesting of his stock options.


7. Mandatorily Redeemable Preferred Stock
The Board of Directors is authorized without further action by the Company's stockholders, to issue 9,100,000
shares of Preferred Stock, in one or more series and to fix the rights, preferences and privileges thereof.

8. Stockholders' Equity
Common Stock
The holders of common stock are entitled to one vote per share on all matters to be voted on by stockholders.
In the event of the liquidation, dissolution or winding up of the Company, the holders of common stock are entitled to share ratably
in all assets remaining after payment of liabilities. The common stock has no preemptive rights or other subscription rights. All
outstanding shares of common stock are fully paid and nonassessable. The Company has reserved 9,684,210 shares of common stock in the
event of conversion of the convertible notes.
The Company has not declared or paid cash dividends as of March 31, 2000.
Warrants
In connection with the leveraged recapitalization, the Company issued to the banks that provided the senior
bank term loan warrants to purchase 701,344 shares of common stock. During the fourth quarter of fiscal 1996, pursuant to the terms
of the warrant agreement, the Company exercised its right to repurchase 40% of the outstanding warrants for an immaterial amount. The
remaining warrants to purchase 420,794 shares of common stock were exercised during the first and third quarters of fiscal 1998.
Stock Option Plans
In November 1995, the Board of Directors authorized and reserved an aggregate of 12,400,000 shares of common
stock for issuance under the 1995 Management Stock Option Plan and the 1995 Stock Option Plan (the "1995 Plan").
In January 1996, the Board of Directors adopted the 1996 Non-Employees Directors' Stock Option Plan (the
"Directors' Plan") to provide for the automatic grant of options to purchase shares of common stock to non-employee directors of the
Company (other than employees or affiliates of Summit Partners, L.P. or Hitachi Metals).
In the event of a merger, consolidation, reverse merger or reorganization, options outstanding under the
Directors' Plan will automatically become fully vested and will terminate if not exercised prior to such event.
No option granted under the Directors' Plan may be exercised after the expiration of ten years from the date it
was granted. The exercise price of options under the Directors' Plan will equal the fair market value of the common stock on the date
of grant. The Directors' Plan will terminate in January 2006, unless earlier terminated by the Board of Directors.
In January 1996, the Board of Directors adopted the 1996 Equity Incentive Plan (the "Incentive Plan"). The
Incentive Plan provides for grants of incentive stock options to employees (including officers and employee directors) and of non-
statutory stock options, restricted stock purchase awards, stock bonuses and stock appreciation rights to employees (including
officers and directors) and consultants of the Company. During 1999, the stockholders approved an amendment to the Incentive Plan
increasing the total number of shares authorized by 2,500,000 shares. The combined maximum number of shares of common stock
authorized to be issued pursuant to options granted under the Directors' Plan and the Incentive Plan is 5,500,000 shares.

The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standards No. 123 (SFAS 123), Accounting for Stock-Based
Compensation. Accordingly, no compensation cost has been recognized for the
1995 Plan. Had compensation cost for the 1996 Plan been determined based on
the fair value at the grant date for the options granted in fiscal 2000, 1999
and 1998 consistent with the provisions of SFAS 123, the Company's net income
for fiscal 2000, 1999 and 1998 would have been reduced to the pro forma
amounts indicated below (amounts in thousands, except per share):Years Ended March 31,

The effects of applying SFAS 123 on pro forma disclosures of net income and net income per share for
fiscal 2000, 1999 and 1998 are not likely to be representative of the pro forma effects on net income and earnings per share in
future years.
The fair value of each option grant for the Incentive Plan is estimated on
the date of the grant using the Black-Scholes option-pricing model with the following weighted
average assumptions:

Employee Stock Purchase PlanIn January 1996, the Board adopted the Employee Stock Purchase Plan (the "Purchase Plan") covering an
aggregate of 500,000 shares of common stock. Under the terms of the Purchase Plan, employees may elect to contribute up to 15% of
their compensation toward the purchase of shares of the Company's common stock. The purchase price per share is the lesser of 85% of
the fair market value of the stock on the first day of enrollment during the six month offering period or the last day within the six
month offering period (generally April 30 and October 31 of each year). The total number of shares of stock issuable under the
Purchase Plan aggregated 3,000,000 shares as of March 31, 2000. In April 1999, the Company's Board of Directors approved an amendment
to the Purchase Plan, creating a two-year window which allows participants to purchase stock at the lesser of 85% of the fair market
value of the stock on the first day of enrollment or the last day of each of four six-month offering periods. Shares issued under the
Purchase Plan were 1,208,389, 371,103 and 278,255 in fiscal 2000, 1999 and 1998, respectively.
For purposes of pro forma disclosure, the fair value of employee's purchase rights has been estimated using the
Black-Scholes model assuming risk-free interest rates ranging from 4.18% to 6.74% in fiscal 2000, 1999 and 1998. Volatility factors
of the expected market price were 98%, 81% and 69% for fiscal 2000, 1999 and 1998, respectively. The weighted-average expected life
of the purchase rights was six months for 2000 and eight months for fiscal 1999 and 1998.
The weighted-average fair value of the purchase rights granted in fiscal 2000, 1999 and 1998 was $2.93, $7.80 and
$11.48, respectively.

Although realization of the deferred tax assets is not assured, the Company believes that it is more
likely than not that all of the deferred tax assets will be realized. Accordingly, no valuation allowance has been recorded.
At March 31, 2000, the Company had federal net operating loss carryforwards of approximately $71 million, as well
as R&D and AMT credit carryforwards of $10 million, available to offset future taxable income. These net operating loss
carryforwards expire in the years 2009 to 2020. The R&D credit and AMT credit can be carried forward for twenty years and
indefinitely, respectively. Because the Leveraged Recapitalization caused an ownership change, as defined by tax law, the Company's
ability to use its net operating loss carryforwards from November 30, 1995 is limited to $810,000 each year.
At March 31, 2000, the Company also had California net operating loss carryforwards of approximately $31.5 million
which expire in the years 2004 to 2005. In addition, the Company had California R&D credit of $3.6 million which can be carried
forward indefinitely, and $5.8 million Manufacturer's Investment Credit which can be carried forward for eight years.

11. Segment and Geographic InformationThe company operates in one business segment, which is the development, production and marketing of high-
performance thin-film media for use in hard disk drives. The Company primarily sells to original equipment manufacturers in the rigid
disk drive market. The company adopted Statement of Financial Accounting Standards No. 131, "Disclosures About Segments of an
Enterprise and Related Information", (SFAS131) at March 31, 1999. SFAS 131 establishes annual and interim reporting standards for an
enterprise's operating segments and related disclosures about its products, services, geographic areas and major customers. Under
SFAS 131, the Company's operations are treated as one operating segment as it only reports profit and loss information on an
aggregate basis to chief operating decision makers of the Company.
The following table presents information about reportable segments by geography. Revenue is allocated to segments
based on the location to which the products were shipped.

12. 401(K) PlanThe Company has a deferred tax savings 401(k) plan and generally matches 50% of employee contributions up to
4% of gross salaries. The employer contributions do not vest until the employee's second year of service, at which time the
contributions vest 100%. All regular, full-time employees are eligible to participate under the plan. The Company contributed to the
plan approximately $0.6 million, $0.6 million and $0.5 million in fiscal 2000, 1999 and 1998, respectively.


13. Subsequent Event
In April 2000, the Company entered into a definitive merger agreement with Komag, Incorporated (Komag). Komag
designs, develops, manufactures and markets high-performance thin-film disks. Under the terms of the definitive merger agreement,
each issued and outstanding share of HMT stock will be converted into 0.9094 shares of the Komag's common stock. The merger will be
accounted for under purchase accounting and is subject to customary closing conditions, including regulatory approvals, the approval
of both companies' shareholders and lenders. The merger is expected to close in the third quarter of calendar 2000. If the merger
agreement is terminated by Komag or HMT upon the occurrence of a triggering event as defined in the definitive merger agreement, the
non-terminating party will pay the terminating party a termination fee of $5 million.
