Patent ID: 7061850

Claim:
A recording method for an optical recording medium, for recording medium identification information for optically distinguishing the medium by using an optical recording medium provided with a main information area capable of recording an information signal and a subsidiary information area for recording subsidiary information that is different from the information signal, which are divided in a radial direction of a disc-shaped substrate, wherein an information layer for recording the information signal in the main information is provided also in the subsidiary information area, and by emitting a light beam to form a light spot to the information layer of the subsidiary information area, the method comprising recording the medium identification information in the information layer of the subsidiary information area by scanning the light beam in a manner such that a previously scanned light spot partially overlaps the light spot adjacent thereto in a tangential direction of the optical recording medium and a previously scanned light spot adjacent thereto in a radial direction of the optical recording medium.
