ABSTRACT:
Address information is recorded on an optical recording medium having groove portions and land portions. The groove portions form a recording track and are spaced at a constant track pitch. The land portions extend between the groove portions. The address information represents the positions of places on the optical recording medium. The recording of the address information is implemented as follows. The address information is converted into words of a self-synchronizable code. The words of the self-synchronizable code are subjected to bi-phase modulation to generate a bi-phase-modulation-result signal. The bi-phase modulation causes frequency modulation. Thus, the bi-phase-modulation-result signal is a frequency-modulation-result signal. The frequency-modulation-result signal is recorded on at least one sides of the groove portions to form wobble of the recording track.
