摘要：
A method for recording address information to an optical disc (5) by forming a wobbled groove is provided. The method includes steps S1 to S3. In step S1, there is generated address information composed of a sync signal, address data and an error correction code for the address data. In step S2, a carrier signal is multiplied by the address information to generate a phase modulation signal. In step S3, there is formed on the optical disc (5) a spiral groove wobbled adaptively to the phase modulation signal.
