Abstract: Disclosed is a data search system for searching the data sync pattern by using a physical address or by detecting the falling edge of the blank area end. The data search system comprises a first data start indicator, a second data start indicator, a decision circuit, a window generator and a data sync pattern search circuit. The first data start indicator generates a first start search signal indicating a first start position. The second data start indicator generates a second start search signal indicating a second start position. The decision circuit selects to output one of the start search signals. The window generator generates a window interval starting from the start position. The data sync pattern search circuit searches a data sync pattern of the data in the window interval to determine the data following the data sync pattern.

Abstract: The present invention provides a method for calibrating focus positions of a pickup head. The pickup head is in a focus position of a predetermined distance from an optical recording medium for producing a recording light beam of a predetermined power for recording corresponding data onto the optical recording medium. A predetermined position adjustment procedure is performed to adjust the focus position of the pickup head during data recording. The procedure comprises the steps of sensing a reflected light beam from the optical recording medium by means of a sensor to generate a corresponding write RF signal; searching an extreme value of the write RF signal and obtain a target focus position corresponding to the searched extreme value; and adjusting the pickup head to the target focus position, so as to enable further data recording onto the optical recording medium by the pickup head in the target focus position.

Abstract: A light beam is scanned on a track of a recording medium, the track having a first track region and a second track region, each track region having a physical property that has recurring deviations. A wobble signal is derived from the light beam, the wobble signal having information associated with the recurring deviations. Whether the light beam is at the first track region or the second track region is determined based on a frequency, a period, or a pulse width of the wobble signal.

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.
