ABSTRACT:
An optical disk apparatus is disclosed. A light emitting element emits a laser beam directed to a recordable optical disk. A driver rotates the optical disk. A first optimum recording power obtaining part performs test recording on the optical disk while the optical disk is rotated by the driver and output power of the light emitting element is varied so as to obtain an optimum recording power based on a reproduction signal in a test recorded area. A temperature measuring part measures the temperature in the vicinity of the light emitting element. A memory stores the optimum recording power obtained by the first optimum recording power obtaining part and the measured temperature when the optimum recording power is obtained. A temperature-dependent recording power obtaining part refers to the optimum recording power and the associated temperature stored in the memory so as to obtain an optimum recording power according to the temperature measured by the temperature measuring part in real recording. A target recording power setting part sets the optimum recording power obtained by the temperature-dependent recording power obtaining part to a target recording power in the real recording.
