Optical disk recording apparatus and optical recording method

摘要

An optical disk recording apparatus includes an optical pickup (6) that emits laser light to illuminate a recording surface (2A) of an optical disk (2), receives reflected light resulting from the laser light reflected off the recording surface (2A), and generates a light reception signal based on the thus received reflected light; a laser power controller that sets a laser power setting and controls the power of the laser light emitted from the optical pickup based on the thus set laser power setting; and a signal generator (9) that, when a plurality of trial write areas provided on the recording surface of the optical disk are successively illuminated with the laser light in order to write trial write data, generates a timing notification signal that notifies laser arrival timing when the laser light sequentially reaches trial write start positions of the plurality of trial write areas based on the light reception signal generated by the optical pickup (6).
