Abstract: A detector is scanned across an optical storage medium having groove tracks and land tracks, each track having a wobble structure, to detect light reflected from the optical storage medium. A wobble signal and a tracking error signal are generated based on an output of the detector, and the wobble signal is sampled according to the tracking error signal. A determination about whether the detector is at the groove track or the land track is made based on the tracking error signal and a comparison of sampled values of the wobble signal.

Abstract: A data search system for searching a data sync pattern stored in an optical disc by using a physical address is disclosed. The data search system comprises a physical address decoder, a data start indicator and a data sync pattern search circuit. The physical address decoder decodes a physical address signal read from the optical disc to obtain the physical address of a current position. The data start indicator generates a start search signal when the pickup head indicates a predetermined physical address to decide a start position. The data sync pattern search circuit searches the data sync pattern of the data from the start position to determine a cluster area of the data following the data sync pattern. The data search system further comprises a window generator, generating a window interval starting from the start position to search the data sync pattern therein.
