SEMICONDUCTOR DEVICE, METHOD FOR GENERATING RECORDING STRATEGY, AND PROGRAM FOR GENERATING RECORDING STRATEGY

摘要

PROBLEM TO BE SOLVED: To highly efficiently generate a recording strategy capable of achieving further high-quality recording.;SOLUTION: A semiconductor device (4) mounted on an optical disk device (100) for controlling data writing and reading with respect to an optical disk (1) performs, on the basis of error information that is generated on the basis of the reproduction signal (S04) read from the optical disk and accommodated to a phase deviation of a reproduction signal to a channel clock signal (301) for the data reproduction: a first step (F01 and F03) for adjusting the recording strategy such that values of error information related to a plurality of recording marks subjected to an evaluation are minimized as a whole; and a second step (F04) for adjusting the recording strategy such that the values of the error information related to a desired recording mark are minimized.;COPYRIGHT: (C)2012,JPO&INPIT
