ABSTRACT:
A data processing method for a holographic data storage system includes in a writing operation, receiving a plurality of digital data groups; modulating the digital data groups to a plurality of corresponding digital matrixes, wherein each of the digital matrix comprises a digital data group and a plurality of digital redundancies; arraying the digital matrixes on a data plane to form an image information, wherein the image information has more opaque pixels than transparent pixels; and storing the image information in a storage medium; and in a reading operation, receiving the image information; 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; demodulating the analog matrixes to a plurality of corresponding analog data groups; and transforming the analog data groups into a plurality of digital data groups by using a soft decision apparatus.
