Paper Abstract

Imaging page-oriented optical data storage, with its high bit packing density and many parallel readout channels, offers a solution for high capacity data storage with fast data transfer rate. As in any data storage system, increasing the packing density increases the effect of inter-symbol interference (ISI) and inter-page interference (IPI). We describe a combination of modulation encoding/decoding and error correction that overcomes this interference allowing high packing density in the presence of noise while maintaining acceptable bit error rate (BER). We also describe an extension of the algorithm to multi-level (grayscale) encoding.
