ABSTRACT:
A plurality of types of writable discs on which wobbles having a predetermined frequency containing absolute addresses and/or various pieces of information on the writable discs can be discriminated by controlling only focusing and using an amplitude of a wobble signal or a wobble PLL lock signal that has passed through a phase locked loop. Accordingly, a discrimination time can be reduced and a disc in an unrecorded state can also be discriminated.
