Optical recording method and control

摘要

A method of overwrite optical recording with a first recording data transmission speed. In accordance with the method data which has been written, is verified for errors. When the number of errors exceeds a predetermined level, the data is re-recorded at the same location. The re-recording is either: 1) conducted with the same conditions; 2) conducted with a higher low level laser beam intensity; 3) conducted with the low level and high level laser beam intensities reversed; or 4) conducted after conducting a test recording and resetting the laser beam modulation intensity. <IMAGE>
