OPTICAL DISC APPARATUS AND METHOD FOR OPTICAL POWER STUDY AND DETECTING THE WRITING POWER THEREOF

摘要

An optical disk apparatus, an optical output learning method thereof, and a writing power detecting method thereof are provided to perform the optical output learning while maintaining a servo part in a predetermined area of an optical disk for lessening the optical output learning time. An optical disk apparatus includes an optical pick up comprising a light source and an actuator driving a lens for forming light spot, and a servo controlling the optical pick up. The optical pick up is moved to a test area of the optical disk where OPC(Optical Power Calibration) for detecting the optimal recording power is performed(S440). Laser beam is emitted by applying an optical output signal to the light source in the predetermined area of the optical disk. The optical output characteristics of the light source are checked by using the optical output signal and the optical output of the emitted laser beam.
