Patent ID: 7898915

Claim:
An optical disc apparatus comprising: a recording module configured to record data on a recording type optical disc comprising first and second layers with laser light of a first recording power set for the first layer and laser light of a second recording power set for the second layer; and a controller configured to record test data respectively on the first and second layers while changing the first and second recording powers, to reproduce the recorded test data in order to determine a first recording power for the first layer and a second recording power for the second layer, and to set the first and second recording powers determined in the recording module, wherein the controller is configured to record the test data on the first layer in order to determine the first recording power while changing the recording power with a predetermined search width and a first predetermined center value of the first layer of the optical disc, to correct a second predetermined center value of the second layer of the optical disc on the basis of the first predetermined center value and the first recording power, and to record the test data on the second layer while changing the recording power with the predetermined search width and the corrected second predetermined value in order to determine the second recording power.
