Summary form only given. It has long been known that volume holography allows multiple pages of data to be stored in the same volume, therefore allowing densities exceeding the diffraction limit for 2-dimensional optical storage. The attraction, is storage of individual Mbit data pages addressed by changing either the angle, wave-length, or phase code of the reference beams, resulting in the rapid parallel storage and retrieval of digital data. Although this technology has been proposed since the 1970's it has failed to achieve viability. Our team has made great strides toward resolving the key problems with the technology. First, a new series of methods for recording multiplexed holograms has been developed. These techniques can be implemented with an uncomplicated mechanical geometry, individual holograms are addressed by a simple translation of the media. In addition, for one particular technique, phase correlation multiplexing is reported.
