Abstract
We defined a new measure called the partial response signal-to-noise ratio (PRSNR) to evaluate signal quality in partial response maximum likelihood (PRML) detection, instead of measuring jitter. This PRSNR was adapted to optimize the write conditions of high-density optical recording in a PR(12221)ML system with blue laser detection. We confirmed that optimum power control (OPC) with PRSNR was able to accurately search for the optimum power of discs and that it was able to do this in a short time occupying less disc area. These results denote that it was sufficiently useful for actual optical disc drives. We also confirmed the feasibility of adjusting a write strategy with PRSNR.
