Holographic data storage developer Inphase Technologies has launched the world's first prototype of a holographic storage drive.
The prototype is the foundation for Inphase's family of Tapestry holographic drives, with data capacities that range from 200 GB to 1.6 TB on a single disk.
The prototype drive records data into Inphase's patented two-chemistry Tapestry photopolymer WORM material. The recording material is 1.5 mm thick and is sandwiched between two 130 mm diameter transmissive plastic disk substrates. Hitachi Maxell developed a new cartridge that provides maximum protection for the light-sensitive recording material.
The prototype arranges some 1m bits of data onto a single page, which is recorded with a single flash of a 407 nm laser beam. Multiple pages of data, referred to as a book, are recorded on one spot on the disk, providing approximately 12MB of data in a single book location.
The prototype drive includes all drive subsystems such as the auto load/unload mechanics, servo system, holographic read/write head, data channel and electronics.
