Holographic Versatile Disc

Holographic recording technology records data on discs in the form of laser interference fringes, enabling existing discs the same size as today's DVDs to store as much as one terabyte of data (200 times the capacity of a single layer DVD), with a transfer speed of one gigabyte per second (40 times the speed of DVD). This approach is rapidly gaining attention as a high-capacity, high-speed data storage technology for the age of broadband.

Optware Corp. was established in 1999 as a development venture to find ways of incorporating holographic recording technology, seen as the heart of the high-capacity optical discs of the future, in commercially viable products. The Company's arsenal of valuable patents includes collinear holography, a technique that enables great simplification of optical systems.

* The collinear holography technique
Optware's exclusive development of the collinear holography technique is part of its effort to make holographic recording technology practical. A patented technology originally proposed by Optware founder and chief evangelist Hideyoshi Horimai, collinear holography combines a reference laser and signal laser on a single beam, creating a three-dimensional hologram composed of data fringes. This image is illuminated on the medium using a single objective. Using this breakthrough mechanism, Optware dramatically simplified and downsized the previously bulky and complicated systems required to generate holograms. Further enhancements were achieved with Optware's exclusive servo system. The introduction of this mechanism enabled reduced pickup size, elimination of vibration isolators, high-level compatibility with DVD and CD discs and low-cost operation, effectively obliterating the remaining obstacles to full commercialization.
