Patent ID: 8000204

Claim:
A data processing method for a holographic data storage system, comprising steps of: in a writing operation, (a) receiving a plurality of digital data groups; (b) modulating the digital data groups to a plurality of corresponding digital matrixes, wherein the modulating step includes steps of: (b-1) adding digital redundancies into each of the digital data groups, and (b-2) arraying the digital data groups with corresponding digital redundancies to form the corresponding digital matrixes; (c) arraying the digital matrixes on a data plane to form an image information, wherein the image information has more opaque pixels than transparent pixels; (d) storing the image information in a storage medium; in a reading operation, (e) receiving the image information; (f) transforming the image information into a plurality of analog matrixes, wherein each of the analog matrixes comprises an analog data portion and an analog redundancy portion; (g) demodulating the analog matrixes to a plurality of corresponding analog data groups; and (h) transforming the analog data groups back to the plurality of digital data groups by using a soft decision apparatus.
