Verfahren zur Erfassung von Pitmustern.

摘要

A recording and/or reproducing apparatus includes a detection unit for detecting a tracking error detecting pit pattern or a sector mark from a detection signal from an optical head adapted to record and/or reproduce data signals on or from an optical disk, on which tracking error detecting pits or sector marks are accorded with a predetermined offset from the center of the recording track. The detection unit is adapted for detecting the tracking detecting pit pattern or the sector mark on the basis of the bit data pattern and the amplitude pattern of the detection signal from an optical head.
