We propose a novel trellis decoding technique for soft-output decoding of 17 parity preserve/prohibit repeated minimum transition runlength (PP) code. The trellis of the 17 PP code has 21 states and 79 branches. We applied the Bahl-Cocke-Jelinek-Raviv (BCJR) algorithm to the trellis to obtain a soft-input soft-output (SISO) decoder. Using this SISO decoder, we have developed a turbo-coded 17 PP system for optical recording. It is experimentally confirmed that the turbo-coded 17 PP system effectively improves the bit error rate (BER) of high-density optical storage.
