Abstract
An optical disc recording apparatus 100 comprises a temperature detecting circuit 141 for detecting a temperature of an optical disc 200 and corrects a laser power for discolorating a discoloration layer of the optical disc 200 in accordance with the temperature detected by the temperature detecting circuit 141 in order to cancel a change in the temperature of the optical disc 200. The optical disc recording apparatus 100 can record a high quality visible image on an optical disc without a printer.
Claims4
