ABSTRACT:
Identification information is recorded by irradiating a laser beam to a predetermined area of an information recording medium by securely changing a land to a pit.A pair of land and pit is formed in the predetermined area of the information recording medium. A laser beam is irradiated to this pair to record the identification information. Accordingly, by applying a laser beam to this area, a land serving as one of the pair is surely changed to a pit so that the identification information can surely be recorded by irradiating a laser beam to the predetermined area. The remaining pit of the pair remains as a pit even when the laser beam is irradiated. Moreover, the laser beam may not be irradiated to the pit.
