High speed CMOS camera chip used in holographic drive

5 October 2005 News

InPhase Technologies is using Cypress Semiconductor's high-speed custom CMOS camera chip for the world's first holographic storage drive. InPhase's Tapestry drive, now in prototype phase, was demonstrated publicly at IBC2005 in Amsterdam.

Cypress' ultrasensitive and ultrafast CMOS image sensor enables high-speed (500 fps) reading of data. The InPhase prototype demonstrates a new generation of storage - well beyond DVD, magnetic tape and disk. The initial Tapestry product holds 300 GB of data with a transfer rate of 20 MBps - ideal for high-definition recording.

Holographic storage records data throughout the volume of the recording material, and not only on the surface. A data page of approximately 1 million bits is recorded in one laser flash. Each page is located at a unique address within the material and several hundred pages of data, each with their own unique address, are recorded in the same location. A collection of pages is referred to as a book, and not only can pages overlap, but also books of data, which dramatically increases storage density.
