Abstract
Page-oriented optical memories (POMs) have the potential to become very high capacity and throughput data storage devices. During readout, data stored in a POM system implemented, e.g. as a volume holographic memory [1,2], may be distorted by a combination of noise sources present in the system, such as the gaussian profile of the beam, misalignment of the various optical components, blurring due to low pass filtering, scattering, and others. Such effects may substantially degrade the quality of the retrieved data and cause a number of bits to be incorrectly identified as 0 or 1 (assuming binary data). Thus, an error correcting scheme is needed to improve the reliability of the system.
