Patent ID: 8411539

Claim:
An optical disc recording device, provided with: an optical pickup for irradiating an optical disc with light and for using a photodetector to detect return light from the optical disc; and a determination unit for changing a recording power value of the optical pickup and writing test data onto a test region of the optical disc to determine an optimum recording power for the optical pickup, wherein: in a case where the optical disc having been mounted in the optical disc recording device is a write-once optical disc provided with only one or two recording layers for playing back or recording information by being irradiated with a laser beam of a specific wavelength band, the determination unit changes the recording power value of the optical pickup within a range from (100−A) % of a reference recording power value corresponding to a recording layer for writing the test data of the optical disc mounted in the optical disc recording device, to (100+B) % of the reference recording power value corresponding to the recording layer for writing the test data of the optical disc mounted in the optical disc recording device, and in a case where the optical disc mounted in the optical disc recording device is a write-once optical disc provided with three or more recording layers for playing back or recording information by being irradiated with a laser beam of a specific wavelength band, the determination unit changes the recording power value of the optical pickup within a range from (100−C) % of the reference recording power value corresponding to the recording layer for writing the test data of the optical disc mounted in the optical disc recording device, to (100+D) % of the reference recording power value corresponding to the recording layer for writing the test data of the optical disc mounted in the optical disc recording device, A, B, C, and D all being set to values greater than 0 and less than 100, and D being set to be lower than B.
