摘要：According to the present invention, there is provided a method of recording aunique ID to a read-only optical disc based on the 17PP modulation. The read-only

optical disc () has set thereon a specific physical cluster to which a unique ID is to berecorded. With user data to be recorded to the specific physical cluster being made allzero (0), a pit/land pattern is formed, and a molding machine using a molding die is usedto form many optical discs in the common manner. Thereafter, an ID unique to eachoptical disc is generated, and a land in a predetermined position in the specific physicalcluster is transited to a pit by irradiating high-power laser light to the land

correspondingly to the bit information, so that the pit/land pattern will comply the 17PPmodulation rule even after the transition of the land to the pit.
