Application of Low Density Parity Check Codes to High-Density Optical Disc Storage Using 17PP Code

摘要

We are developing a high-density recording method for optical disc storage. To improve the density of optical recording systems and increase the operational margin, we previously optimized the PR17PP trellis by merging the PR(1221) trellis and we achieved a higher recording density in optical disc storage. In this paper, we propose a new high-density low density parity check (LDPC)-coded PR17PP system with PR(12221)-ML. We experimentally confirmed that the system significantly increases the tilt margin of 36.0GB optical disc with Blu-ray disc parameters.
