PURPOSE: A method for processing an optical disk is provided to be able to laser-process plural locations by once process scanning. CONSTITUTION: A method for processing an optical disk comprises the steps of: performing an optical deflection to a laser beam used for a processing, by use of an optical deflector using an electric field optical effect or an optical deflector using a voice optical effect; and laser-processing a groove and a pre-bit group on a track by once process scanning.
