摘要
A semiconductor device mounted in an optical disk apparatus controls writing and reading of data in and from an optical disk. The device performs first processing for adjusting a write strategy in such a manner that based on error information corresponding to a shift in the phase of a reproduction signal with respect to a channel clock signal for data reproduction, which is generated based on the reproduction signal read from the optical disk, the value of the error information related to a plurality of recording marks to be evaluated becomes minimum as a whole. The device also performs second processing for adjusting a write strategy in such a manner that the value of the error information related to a desired recording mark becomes small.
