RECORDING CONDITION ADJUSTING METHOD OF OPTICAL DISC RECORDING/PLAYING SYSTEM, OPTICAL RECORDING PLAYING DEVICE AND OPTICAL DISC

摘要

A recording condition adjusting method of an optical disc recording/playing system, including the steps of: measuring a playing signal obtained by playing a result written in an optical disc; determining whether or not an asymmetry value calculated from the result of the measuring can be employed for adjustment of recording power; calculating a predetermined statistic according to a peak local maximal value and/or a peak local minimal value of an amplitude of a playing signal according to specified codes from the result in the measuring, in the case of determining that the asymmetry value cannot be employed for adjustment of recording power; and deciding the recording power based on the predetermined statistic.
