Abstract: 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.

Abstract: System and method for content-addressable search of holographically stored data primarily optimized with respect to search performance. A search is performed, by a holographic correlator system, on a structured representation of original data, stored in a holographic data storage medium. In a first aspect, orthogonal phase encoding of both data storage and search pages provides improvement of correlator system signal to noise ratio and dynamic range. In a second aspect, correlator incorporates heterodyne detection of a plurality of correlation signals, obtained by modulation and amplification thereof by a plurality of frequency-shifted reference beams. In a third aspect, the invention provides a method whereby multiple searches can simultaneously interrogate a single data storage location.

A plurality of information bearing light beams in an information bearing light beam arm of a data recording system and a plurality of reference light beams in a reference light beam arm of the data recording system are mutually interfered to store a plurality of spatially separate, spatially modulated light intensity patterns in a holographic data storage medium in a data recording operation. During the data recording operation, the plurality of information bearing light beams are repeatedly circulated through the holographic data storage medium using a resonant cavity formed along the information bearing light beam arm of the holographic recording system.

Abstract: System and method for parallel selection and retrieval of data stored in an optical data storage medium. A holographic data storage medium has a plurality of data sites, each data site containing a plurality of data units recorded as multiplexed holograms. A plurality of light beams are independently controlled to illuminate a different one of the plurality of data sites for selecting and retrieving any one data unit stored at each of the plurality of data sites. The invention enables the simultaneous selection and retrieval of data units stored at a plurality of data sites of the holographic data storage medium, and permits an increase in optical data transfer rate.
