Write control parameter optimizing apparatus, write control parameter optimizing method, recording apparatus, and recording method

摘要

A write control parameter optimizing apparatus for use in a recording apparatus for recording digital data in a recording medium, comprises means for recording random data as data packets by using different write pulse lights determined by increasing and decreasing a write control parameter, means for detecting jitter from each of reproduced data packets, and means for determining an optimal value of the write control parameter according to a detection result of the detecting means.
