ABSTRACT:
An attempt is made to prevent an adequate recording power detection lag from being generated according to data from a defective area at trial writing, by detecting a defective area portion based on a fluctuation of return light when a trial write recording mark is formed, recording it in another portion under the same conditions as the detected portion, and using the information on the recorded area instead of the area in which the defective area was detected at reproduction of the trial writing.
