Optical disk apparatus, optical recording method, optical recording program and storage medium

An optical recording method for an optical disk apparatus having a light emitting element emitting a laser beam directed to a recordable optical disk, a driver rotating the optical disk, and a temperature measuring part measuring a temperature in the vicinity of the light emitting element, the recording method comprising the steps of:

• a first optimum recording power obtaining step obtaining an optimum recording power based on a reproduction signal in an area of the optical disk on which a test recording is performed, the test recording being performed such that the optical disk is rotated by the driver and output power of the light emitting element is varied;
• storing, in a memory, the obtained optimum recording power and the temperature measured by the temperature measuring part when obtaining the optimum recording power, such that the obtained optimum recording power is associated with the measured temperature;
• obtaining the optimum recording power according to the temperature measured by the temperature measuring part in real recording by referring to the optimum recording power and the temperature associated with the optimum recording power that are stored in the memory;
• and
• setting, as a target recording power in the real recording, the optimum recording power obtained in the step of obtaining the optimum recording power according to the measured temperature.
