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 recovery system and method is disclosed. Said data recovery system comprises a maximum-likelihood detector, a non-maximum likelihood detector, signal-length calculator, a determining unit and a selecting unit. The maximum-likelihood detector transforms a digital signal into a first binary signal. The non-maximum likelihood detector transforms the digital signal into a second binary signal. The signal-length calculator calculates a length of the first binary signal and a length of one previous to the first binary signal. The determining unit generates a selecting signal when the length of the first binary signal and the length of one previous to the first binary signal meet a criterion. The selecting unit coupled to the maximum-likelihood detector and the non-maximum likelihood detector, selectively outputs the first binary signal or the second binary signal based on the selecting signal.

A prohibiting time is then determined according to the driving time. The collimator lens is then prevented from moving until the prohibiting time elapses.

Abstract: The invention provides a driving circuit for driving a laser diode of a pickup head. In one embodiment, the driving circuit comprises an automatic power control (APC) module, a clamp value determination unit, and a clamp circuit. The automatic power control module generates at least one power control signal.
