A new efficient modulation code for holographic memory, or 9:12 pseudo-balanced code(9-12PBC), has been developed and evaluated. The proposed code is partitioned into 16 codeword subsets and is decoded in conjunction with Viterbi algorithm. The results of numerical simulations and actual recording experiments show that 9-12PBC gives favorable trade-off between code rate and bit error rate(BER) performance.
