System and method for content-addressable holographic data storage,
primarily optimized with respect to search performance. A structured
representation of original data, such as represented by metadata, is
provided and stored in a holographic data storage medium on which a
search can be performed using a holographic correlator. Phase encoding of
both data storage and search pages provides improvement of correlator
system signal to noise ratio and dynamic range. Heterodyne detection is
also used to provide amplification to a plurality of correlation signals
by modulation thereof by a plurality of reference beams. In another
aspect, increase in the storage density of the holographic data storage
medium and the throughput of a holographic correlator is achieved by
employing a content-addressable storage scheme, using a priori knowledge
of content provided by metadata to organize data according to a
selectable content relationship and store related data as a contiguous
cluster.
