Abstract
An optical disc drive that can carry out recording data to an optical disc such as a format procedure of the optical disc in a relatively short time is provided. An optical disc drivehas a rotation driving mechanism for rotating a loaded optical discat any one of multiple rotational speed (rotation number) levels, an optical pick-upcapable of moving in a radial direction of the loaded optical discto overwrite information (data) onto the optical discby emitting a laser beam thereto, and an optical pick-up moving mechanism including a sled motorfor moving the optical pick-upin the radial direction of the optical disc. In a case that the optical discis a blank disc having no recording history, i.e., in a case of a first recording procedure of the optical disc, the optical disc drivecarries out recording at a recording speed higher than the highest recording speed for overwriting.
