Description:
TECHNICAL FIELD 
       [0001]    The invention relates to the field of hard disk drives. 
       BACKGROUND ART 
       [0002]    Direct access storage devices (DASD) have become part of everyday life, and as such, expectations and demands continually increase for greater speed for manipulating and for holding larger amounts of data. To meet these demands for increased performance, the mechano-electrical assembly in a DASD device, specifically the Hard Disk Drive (HDD) has evolved to meet these demands. 
         [0003]    Advances in magnetic recording heads as well as the disk media have allowed more data to be stored on a disk&#39;s recording surface. The ability of an HDD to access this data quickly is largely a function of the performance of the mechanical components of the HDD. Once this data is accessed, the ability of an HDD to read and write this data quickly is primarily a function of the electrical components of the HDD. 
         [0004]    A computer storage system may include a magnetic hard disk(s) or drive(s) within an outer housing or base containing a spindle motor assembly having a central drive hub that rotates the disk. An actuator includes a plurality of parallel actuator arms in the form of a comb that is movably or pivotally mounted to the base about a pivot assembly. A controller is also mounted to the base for selectively moving the comb of arms relative to the disk. 
         [0005]    Each actuator arm has extending from it at least one cantilevered electrical lead suspension. A magnetic read/write transducer or head is mounted on a slider and secured to a flexure that is flexibly mounted to each suspension. The read/write heads magnetically read data from and/or magnetically write data to the disk. The level of integration called the head gimbal assembly (HGA) is the head and the slider, which are mounted on the suspension. The slider is usually bonded to the end of the suspension. 
         [0006]    A suspension has a spring-like quality, which biases or presses the air-bearing surface of the slider against the disk to cause the slider to fly at a precise distance from the disk. Movement of the actuator by the controller causes the head gimbal assemblies to move along radial arcs across tracks on the disk until the heads settle on their set target tracks. The head gimbal assemblies operate in and move in unison with one another or use multiple independent actuators wherein the arms can move independently of one another. 
         [0007]    To allow more data to be stored on the surface of the disk, more data tracks must be stored more closely together. The quantity of data tracks recorded on the surface of the disk is determined partly by how well the read/write head on the slider can be positioned and made stable over a desired data track. During read/write operations, there is present within the HDD an internally generated air turbulence that is caused by the rotation of the disk(s). Hard Disk Drives with faster disk rotational speeds are subject to increased air turbulence. The generated air turbulence can cause instability in the read/write head during read/write operations. 
         [0008]    With reference to  FIG. 5 , to control some of the generated air flow, e.g., air flow  14  in a hard disk drive, e.g., drive  99 , an air flow bypass channel has been implemented within the structure of housing  13  of HDD  99 , e.g., bypass channel  55 . Air flow bypass channel  55  is able to capture air flow  14 , centrifugally directed outward and which is generated by disk(s)  15  during operation, and recirculate, or channel, air flow  14  so as to control the direction of some of the generated air turbulence. 
         [0009]    There is also an air flow, e.g., air flow  18 , generated by disk(s)  15  and directed toward the suspension and the read/write, generally indicated by dotted line  27 , and which is not captured by air flow bypass channel  14 . To that extent, a spoiler component, e.g., spoiler component  90 , has been developed to further diffuse and/or redirect a generated air flow away from the suspension and read/write head. To incorporate a spoiler  90  into a hard disk drive  13 , a portion of inner wall  51  of air flow bypass channel  55  is removed from and/or omitted during the fabrication thereof, generally indicated by dotted line  40 , allowing installation of spoiler  90 . The removed/omitted portion  40  of inner wall  51  and spoiler  90  are observed not to provide a complete inner wall  51 , thus allowing air flow  14  to escape from bypass channel  55 , as indicated by arrow  50 . 
       SUMMARY OF THE INVENTION 
       [0010]    A spoiler having an integrated wall feature implementable in a hard disk drive. The spoiler includes a structure having a diffuser integrated therewith. The structure further includes an extension emanating there from, the extension configured to complete a wall of a bypass channel in said hard disk drive.

     DETAILED DESCRIPTION 
       [0027]    Reference will now be made in detail to embodiment(s) of the present invention. While the invention will be described in conjunction with the embodiment(s), it will be understood that they are not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. 
         [0028]    Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be recognized by one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well known methods, procedures, and components have not been described in detail as not to unnecessarily obscure aspects of the present invention. 
         [0029]    The discussion will begin with an overview of a hard disk drive and components connected within. The discussion will then focus on embodiments of the invention that provide a spoiler with an integrated bypass channel wall for utilization in HDDs. 
         [0030]    Although embodiments of the present invention will be described in conjunction with a slider integrated in a microactuator, it is understood that the embodiments described herein are useful outside of the art of microactuators, such as devices requiring high frequency transmission between two devices that have relative motion. The integration of the slider and a microactuator is one example of embodiments of the present invention and is provided herein merely for purposes of brevity and clarity. 
       Overview 
       [0031]    With reference now to  FIG. 1 , a schematic drawing of an embodiment of an information storage system comprising a magnetic hard disk file or drive  199  for a computer system is shown. Drive  199  has an outer housing or base  113  containing a disk pack having at least one media or magnetic disk  115 . Although not shown in  FIG. 1 , it is noted that there is an appropriately configured (mated) cover for disposition upon outer housing  113 , such that when the cover is in place, a sealed HDD exists. A spindle motor assembly having a central drive hub  117  rotates the disk or disks  115 , as indicated by arrows  116 . During HDD operation, the rotation of disks  115 , as indicated by arrows  116 , generates an air flow, e.g., air flow  118 , directed toward an actuator  121 , and air flow  156  directed toward an air bypass channel  155 . An actuator  121  comprises a plurality of parallel actuator arms  125  (one shown) in the form of a comb that is movably or pivotally mounted to base  113  about a pivot assembly  123 . A controller  119  is also mounted to base  113  for selectively moving the comb of arms  125  relative to disk  115 . 
         [0032]    In the embodiment shown, each arm  125  has extending from it at least one cantilevered electrical lead suspension (ELS)  127  The ELS may be any form of lead suspension that can be used in a Data Access Storage Device, such as a HDD. A magnetic read/write transducer or head is mounted on a slider  129  and secured to a flexure that is flexibly mounted to each ELS  127 . The read/write heads magnetically read data from and/or magnetically write data to disk  115 . The level of integration called the head gimbal assembly is the head and the slider  129 , which are mounted on suspension (also referred to as a flexure)  127 . The slider  129  is usually bonded to the end of ELS  127 . 
         [0033]    ELS  127  has a spring-like quality, which biases or presses the air-bearing surface of the slider  129  against the disk  115  to cause the slider  129  to fly at a precise distance from the disk. ELS  127  has a hinge area that provides for the spring-like quality, and a flexing interconnect (or flexing interconnect) that supports read and write traces through the hinge area. A voice coil  133 , free to move within a conventional voice coil motor magnet assembly  134  (top pole not shown), is also mounted to arms  125  opposite the head gimbal assemblies. Movement of the actuator  121  (indicated by arrow  135 ) by controller  119  causes the head gimbal assemblies to move along radial arcs across tracks on the disk  115  until the heads settle on their set target tracks. The head gimbal assemblies operate in a conventional manner and move in unison with one another, unless drive  199  uses multiple independent actuators (not shown) wherein the arms can move independently of one another. 
         [0034]    Air flows  114  and  118  can cause instability of slider  129  during HDD operation. To mitigate air flow  114 , a bypass channel  155 , being disposed within housing  113 , is configured to redirect generated air flow  156  away from ELS  127  during HDD operations. Bypass channel  155  includes an intake portion  145 , an exhaust portion  165 , an inner wall structure  151  and an outer wall structure  153 . 
         [0035]    It is noted that generated air flow  118 , due to rotation  116  of disk  115  during HDD operation, is directed toward slider  129  during HDD operation. 
         [0036]    Also included in  FIG. 1  is a region  200  which includes the interface of disks  115  and intake potion  145  of bypass channel  155 . It is with particular attention to region  200  that embodiments of the present invention are drawn. 
         [0037]      FIG. 2A  is an expanded view of region  200  from  FIG. 1  in an embodiment of the present invention. Region  200  includes a spoiler, e.g., spoiler  390 , for diffusing and/or redirecting air turbulence  118  away from slider  129 . Spoiler  390 , mounted upon and within hard disk drive  299 , is shown to include a diffuser portion  380  including three diffusing fin sections  381 ,  382  and  383 , in which fins  381 ,  382  and  383  are interposed between four hard disks  115 . In alternative embodiments, and dependent upon the number of disks  115  present in an HDD, spoiler  380  may have a fewer number or a greater number of fins. Further, in other alternative embodiments, the plurality of fins may be configured such that a fin is present above the top most disk  115 , interposed between other disks  115 , and also present below the bottom most disk  115 . Thus, in the shown example, there would be five fins for the four disks  115 . In yet another embodiment, the number of fins may be equal to the number of disks  115 , such that the upper most disk  115  does not have a fin disposed there above or, alternatively, the bottom most disk  115  does not have a fin disposed there below. 
         [0038]    In an embodiment, fins  381 ,  382  and  383  may be of any shape and size, given functional characteristics and constraints of the HDD into which spoiler  390  is to be implemented. As such, fins  381 ,  382  and  383  may be angular, rectangular, elliptical, oblong, rounded, or a combination thereof, or other shape that can provide diffusion and/or redirection of air turbulence, e.g., air turbulence  118 , away from slider  129 . 
         [0039]    Also in  FIG. 2A , spoiler  390  is also shown to include a tail portion  391  having a vertical contour  301  that is integrated therewithin and extends distally from diffuser portion  380  of spoiler  390 , in an embodiment of the present invention. In the present embodiment, tail portion  391  is shown extending in the direction of vertical contour  201  of inner wall  251  of bypass channel  255 . Tail portion  391  further includes a horizontal contour  302  that is oriented toward and mated with horizontal contour  202  of inner wall  251  of bypass channel  255 . 
         [0040]    A portion of inner wall  251  of bypass channel  255  has been contoured and/or had a portion omitted there from during fabrication, leaving a remaining vertical surface, e.g., vertical surface  201 , and a horizontal surface, e.g., horizontal surface  202  (relative to vertical surface  201 ), to facilitate installation of spoiler  390 , in accordance with an embodiment of the present invention. 
         [0041]    Contours  301  and  302  of tail portion  391  of spoiler  390  are appropriately contoured to mate with contours  201  and  202  of inner wall  251 , or vice versa, such that when installed in HDD  213 , spoiler  390  completes inner wall  251  of bypass channel  255 . When installed, tail portion  391  provides a completed inner wall  251  for preventing air flow  114  from escaping bypass channel  255 , in accordance with an embodiment of the present invention.

Tail portion  391  of spoiler  390  is shown to include a compound offset angle step contour  331  having an angled step  335  and an angled step  336 , offset from step  335 , such that steps  235  and  335  and steps  236  and  336  are associatively mated. 
         [0045]      FIG. 2E  is a top down block diagram of yet another contour that is implementable in inner wall  255  and tail portion  391  of spoiler  390 , in accordance with an embodiment of the present invention. Vertical surface  241  of inner wall  251  shows a singularly beveled contour, e.g., bevel  245 . Tail portion  391  of spoiler  390  is shown to include a vertical surface  341  having a singularly beveled contour, e.g., bevel  345 , such that bevel  245  and bevel  345  are mated.

         [0047]    Still referring to  FIGS. 2A-2E , it is further noted that the contours applied to the vertical surface of inner wall  251 , e.g., contours  211 ,  221 ,  231 ,  241  of  FIGS. 2B-2E  respectively, as well as being applied to the vertical surface  311 ,  321 ,  331 ,  341  of tail portion  391  of spoiler  390  are of some of the implementable contours, and as such should not to be construed as a limitation, but rather as examples of possible contours. Further, those contours may be singularly or combinationally implemented upon the vertical surfaces and/or the horizontal surface  202  of inner wall  251  as well as the mated horizontal surface of tail portion  391 , e.g., horizontal surface  302 , in accordance with an embodiment of the present invention.
