ABSTRACT:
A fast optimum power control method is disclosed, with a laser power level being adjusted in a predetermined sequence at an ADIP/ATIP frame of an optical recording medium. Jitter is measured at each ADIP/ATIP frame in order to obtain an average jitter value for that particular frame, and hence power level.
