A method for recording address information to an optical disc ( 5 ) by forming a wobbled groove is provided. The method includes steps S 1 to S 3 . In step S 1 , there is generated address information composed of a sync signal, address data and an error correction code for the address data. In step S 2 , a carrier signal is multiplied by the address information to generate a phase modulation signal. In step S 3 , there is formed on the optical disc ( 5 ) a spiral groove wobbled adaptively to the phase modulation signal.
