A METHOD AND APPARATUS OF OPTIMIZING WRITE PARAMETERS FOR A REWRITABLE OPTICAL DISC

摘要

A method of optimizing write parameters for a rewritable optical disc comprises the steps of: reading out (310) predefined write parameters from the rewritable optical disc, which predefined write parameters comprise a power indicator Pwind and an initial Epsilon value e, selecting (320) a Tmp from a range [8T/40, 14T/40] and a dTtop from a range [11T/40, 17T/40], where Tmp is a multiple pulse time, dTtop is a first pulse lead-time, and T is a clock period, adjusting (330) e to adapt to a jitter value according to the value of Pwind, and generating (340) an optimized write power Pw based on the jitter value and the adjusted e.
