Holographic Versatile Disc: High speed information storage systems

Holographic information storage systems (HISS) 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 systems, such as laser technology, spatial light modulators (SLM) and complementary metal-oxide semiconductor (CMOS) image sensors. Holographic Versatile Disc (HVD) system using Collinear Technology, a new technology for HISS, is proposed and demonstrated by OPTWARE Corporation. This technology can produce a small, practical HISS more easily than conventional 2-axis holography.
