Abstract:
HOLOGRAPHIC information storage systems (HISSs) have been a good candidate
for a volumetric recording technology, due to their large storage capacities and high
transfer rates. Recently, revival of activity in HISS has resulted from the dramatic
developments in the requisite components for such a system, such as laser technology,
spatial light modulators (SLMs), and complementary metal–oxide semiconductor (CMOS)
image sensors. Within the last several years, unique demonstration platforms using
digital volume holography have been proposed . We call these HISSs conventional twoaxis
holography. The Holographic Versatile Disc (HVD) system using collinear
technology, a new technology for HISSs, is proposed and demonstrated by Optware
Corporation, Kana- gawa, Japan
Holographic memory systems have been around for decades. They offer far more storage
capacity than CDs and DVDs -- even "next-generation" DVDs like Blu-ray -- and their
transfer rates leave conventional discs in the dust. So why haven't we all been using
holographic memory for years now?
There are several hurdles that have been holding holographic storage back from the realm
of mass consumption, including price and complexity. Until now, the systems have
required a cost-prohibitive level of precision in manufacturing. But recent changes have
made the holographic versatile disc (HVD) developed by Optware a viable option for
consumers.
In this article, we'll find out how the HVD works, how it has improved upon previous
methods of holographic storage and how it stacks up to Blu-ray and HD-DVD.
