ABSTRACT:
An optical recording method and an optical recording apparatus enable recording information on recording tracks substantially corresponding to ideal reference tracks, on an optical recording medium without preformatted tracks. The optical recording medium is scanned by a rotating optical scanning system using a scanning light beam emitted by an external light source to record information on the optical recording medium. Prior to recording the information on the optical recording medium, information recorded on a reference track recording medium provided with ideal reference tracks is reproduced in a tracking control mode to acquire tracking control data and the tracking control data is stored in a waveform memory. In recording information on the optical recording medium, the rotating optical scanning system is controlled on the basis of the previously stored tracking control data so that the scanning spot traces recording tracks corresponding to the ideal reference tracks.
