ABSTRACT:
In a land pre-pit address demodulating device DM for detecting land pre-pit address information during recording to a DVD-R/RW-disc, a tracking error signal TE is muted by a first reference potential Vref1during a period in which the tracking error signal TE is generated from a reflected laser beam having a power for recording a mark, an RF residual component is removed from the tracking error signal TE, and the tracking error signal TE from which the RF residual component has been removed is compared with a second reference potential Vref2, thereby detecting a land pre-pit address signal.
