In order to apply iterative detection to the optical-storage channel, we have developed a dc-controllable 8-state rate-2/3 (1, 7) run-length-limited code with a maximum repeated minimum transition-run length of 5. The code can halve the size of hardware for a soft-input soft-output decoder, compared with that of the conventional 17PP code employed in the Blu-ray disc optical-storage system. The code also outperforms the 17PP code in bit-error rate when a low-density parity-check code is concatenated.
