ABSTRACT:
An optical disk device includes a recording power acquiring unit which acquires recording power, a recording unit which records data on an optical disk set in a device body by irradiating laser light of the recording power onto the optical disk, and a laser power control unit which controls power of the laser light. Preferably, the recording power is suited to record data on the optical disk, and the laser power control unit gradually decreases the power of the laser light irradiated in a linking region from the recording power based on a first prescribed condition when recording of data by the recording unit is ended and gradually increases the power of the laser light irradiated in the linking region to the recording power based on a second prescribed condition when the recording of data by the recording unit is started.
