Abstract

The capacity of conventional holographic memories is limited to about 10⁸ bits. For use with computers, however, several orders of magnitude more are required. One solution is to store information in moving hologram tracks; this yields an order of magnitude more storage density. Alternatively, block-organized memories could be equipped with nonintegrated, large area detector arrays. This allows to reach 10¹⁰ bits. Finally, we consider the hologram plate and its detector and page composer matrices as a compact storage module, and assemble many modules into a memory having one laser, deflector, and additional passive beam dividers. This allows random access to virtually unlimited capacities.
