ABSTRACT:
An optical recording method according to the invention is provided such, that when an optical pickup (2) is moved over an optical disk (1), the optical pickup (2) being positioned onto the target track location, record marks are recorded on the optical disk (1) by a light beam irradiated onto the optical disk (1) through the optical pickup (2). An irradiation position of the light beam is offset during recording by a predetermined amount to a track at the recording direction side relative to the target track location, and a record mark is formed on a target track by the offset light beam.
