ABSTRACT:
A last optimum parameter value control method is disclosed, with a laser parameter value 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 parameter value.
