Growing demand for high capacity, compact, low cost, data storage for consumer products (e.g. video), for desk top computers, and for large data base systems is surpassing the capabilities of-present day magnetic disk drive and optical CD-ROM technologies. Due to advances in volume holographic storage media a number of university and industrial research laboratories are pursuing the development and commercialization of high capacity holographic data storage systems. In order to effectively exploit this potential, new types of optical input/output devices are needed. In this STTR Displaytech, working in collaboration with MIT, proposes to develop a-compact optical read/write head for use in MIT's room temperature holographic memory program. The optical read/write head will be an important component for the eventual production of commercial holographic memory systems. This new electro optic device should enable the largest demonstration of single page data transfer ever reported (l,000 x 1,000 pixels), enabling storage of more than 100 Gbytes of information in the holographic memory. The electro-optic read/write head, in conjunction with the room temperature holographic material, will enable the first system integration of a very high capacity holographic memory and has high commercial payoff. Successful completion of the proposed work will result in a prototype optical |read/write head which will raise the performance and commercial feasibility of optical holographic memory systems. It will be of immediate use in MIT's room temperature holographic memory program, and will be a key building block for the commercialization of holographic memory technology.
