Abstract

A write strategy calibration system for an optical media playback device comprises memory for storing a write strategy table. A control module generates a write signal to write a training pattern to an optical storage medium according to calibration data stored in the write strategy table. A write strategy analysis module receives a read signal Indicative of the training pattern written to the optical storage medium and adjusts the calibration data according to the read signal.
