Patent ID: 8270272

Claim:
A recording power calibration method, for improving seeking stability on a power calibration area, the method being for performing an optimal recording power calibration once when an optical disk is placed into an optical drive, and thus obtaining optimal recording power, wherein a specific area serving as a data recording area during the optimal recording power calibration, and a length of the specific area being such that a plurality of times of optimal recording power calibrations can be performed, the method comprising: an optimal recording power calibration step, for recording, with a plurality of recording powers, a first length of calibration data in the specific area, and calibrating the optimal recording power, wherein a data sector recorded in this step is defined as a calibration recording sector, wherein an optimal recording power calibration has been performed at the optical disk before the optimal recording power calibration step, wherein a blanking area is reserved between the calibration recording sector corresponding to the optimal recording power calibration step and the calibration recording sector corresponding to the optimal recording power calibration step previous.
