Research Trends in Advanced Digital Recording Systems: A Holographic Memory Perspective

Engineering Hall 2430
Featuring: Dr. Shayan Garani Srinivasas, Western Digital Corporation


Digital information storage is one of the fastest emerging technological
areas as there is an ever increasing need to store and recover more
information bits reliably within shrinking media dimensions. Research
and development of successful digital recording systems has been a
truly interdisciplinary endeavor involving materials, electro-mechanical
characterization, communications and signal processing, and systems
engineering guided by underlying physical principles.

This talk will provide a broad overview of the general trend in
advanced data storage research covering several memory prototypes. As
a case study, principles and techniques pertaining to digital
holographic recording will be addressed in detail. The recording and
retrieving of two-dimensional holograms within the volume of a
holographic material is an instance of noisy communications channel.
This talk will address how information-theoretic concepts, channel
modeling, two-dimensional coding and signal processing techniques are
applied towards understanding and realizing the fundamental data storage
limits in holographic channels. Several interesting open theoretical
problems in coding theory of vital practical significance will also be
highlighted within the context of storage research.
