Paper Abstract

We have designed a compact holographic data storage (CHDS) system based on the principle of volume holographic storage and angular multiplexing, using a spherical wave as the reference beam. The CHDS system has large-capacity, high-speed and can retrieve data without changing it, which will provide a revolutionary memory technology. In the experiment, pages of information were recorded and retrieved with the same spherical reference beam. A new method of multiplexing, which is angular multiplexing, furthermore, was developed to maximize the storage capacity, data transfer rate, and minimize the system volume. The main difference between this new method and traditional ones is that we rotate the recording material instead of shifting it. A real experiment system was set up with a volume of 28×18×16cm3 in our laboratory.
