ABSTRACT:
The present invention sets forth a method and a system for calibrating optimized power of an optical pick-up unit of an optical disk drive. The system comprises a micro-processor, and a signal processor. The micro-processor coupled to the optical pick-up unit sets an initial power corresponding to an optical disk, and calculates a predetermined number of power levels to cover the range of the initial power for performing a recording procedure. The signal processor coupled to the micro-processor determines whether a servo state failed during optimized power calibration, and calculates recording performance of each power level. The signal processor transmits the servo state and the recording performance to the micro-processor for determining the optimized power.
