Abstract

PURPOSE: To correct the deviation between postscription pits and a clock and to reproduce information stably with high accuracy by delaying a clock signal generated based upon a playback signal from pre-pits when reproducing postscript data pits recorded in a 2nd area.
CONSTITUTION: A postscript synchronizing pit 54 is recorded at the head of a data pit sequence when the postscript pits 9 are recorded, the phase difference between the playback signal S1 from the postscript synchronizing pit 54 and the clock signal S4 generated based upon the playback signal S1 from the pre-pit is detected at the time of reproduction to give the clock signal S4 such a delay quantity that the phase difference is minimized and then generating a clock signal S5 for data pit sequence reproduction, and the delayed clock signal S5 is used to reproduce the postscript data pits 9. Consequently, the phase difference between the postscript data pits and a pre-format is canceled to improve the reliability of postscript data pit demodulation.
