Course Description
This short course addresses fundamental principles
and issues pertaining to digital holographic data
storage (DHDS). First we begin with a discussion of
fundamental principles of holography, including thesuperposition of plane waves to form a thickdiffraction grating, diffraction from such a grating,and the conditions under which diffraction is
optimized. We present the Bragg effect as the key tosuperimposing multiple holograms inside therecording medium to achieve high densities. Several
optical multiplexing techniques are discussed
including angular, wavelength and phase encoding.
Next we discuss recording properties of two types of
media,
thinfilm
photopolymers
and
thick
photorefractive media. We describe the underlying
physical principles of the photorefractive effect,
methods for long term data storage including
temperature and two-photon fixing, and noise
effects that affect system performance. The
recording and fixing properties of thin film
photopolymer materials are described including free
radical and CROP type media, as well as theirmechanical properties as they affect holographic
data storage.
Digital channel coding and error correction schemes
are discussed in the context of holographic data
storage. Emphasis is placed on techniques that are
optimized for two-dimensional or paged basedstorage systems. Examples of different coding
techniques are given and performance is analyzed interms of capacity as a function of code rate.
Two different experimental architectures are
discussed in detail, the thin film polymer based
systems, typically in a rotating disc format, and the
no-movingparts
implementationsofthickphotorefractive crystals. Examples will be discussedof an extremely fast access storage implementation
using a-o modulators providing data access in a few
microseconds, and an ultra-fast disc based storage
system having a transfer rate of over 15 Gbit/sec.
Finally, optimization of system performance andpractical implementations developed under the
DARPA sponsored PRISM and HDSS consortia will be
reviewed. We will conclude with updates on thelatest reported performance specifications of various
HDS implementations around the world.

SC251: Partial Response Maximum Likelihood(PRML) Principles and Technologies for Optical
Data Storage
Vijayakumar Bhagavatula, Carnegie Mellon Univ.,
USA
Course Description
As recording densities in optical data storage
systems increase, read channels must cope withincreased intersymbol interference (ISI) anddecreased signal-to-noise ratio (SNR). ISI, in theory,can be completely eliminated, but this leads to noise
amplification and significant reduction in SNR. A
practical alternative is to employ partial response(PR) equalization that aims at controlling the ISI
instead of eliminating it. Since PR equalization does
not try to eliminate ISI, it does not amplify the noise
significantly. Since PR methods lead to known ISI
patterns, optimal data detection can be achieved
using maximum likelihood (ML) techniques such as
Viterbi Algorithm (VA). In this course, we will
discuss the basics of PRML and illustrate how PRML
can be applied to optical data storage.
Benefits and Learning Objectives
This course will enable you to:

·
·
·
·
·
·

Quantify the advantages of using PRML
approaches;
Evaluate various partial response (PR) targets
for optical data storage channels;
Design equalizers capable of achieving thedesired PR targets;
Apply Viterbi algorithm to implement the
maximum likelihood data detection;
Quantify the performance of PRML systems
using appropriate performance criteria; andLearn how PRML approaches being suggested
for advanced optical data storage systems.

Intended Audience
Engineers, scientists and managers who need tounderstand the advantages and implications of PRML
for optical data storage. Basic knowledge in signals
and systems and probability theory and randomvariables will be assumed and any additional
necessary background will be provided.
