    摘要： A filter, including a direct-current (DC) tracking unit, a subtracter and a control unit, is provided. The DC tracking unit extracts a DC component of a radio-frequency (RF) signal and accordingly generates a level signal. The subtracter subtracts the level signal from the RF signal to generate a RF coupling signal. The control unit determines whether to transmit a setting signal to the DC tracking unit according to the level variation of the RF coupling signal, so as to adjust a characteristic parameter of the DC tracking unit.

    摘要： A control system determines read performance of an optical storage device according to lock performance of a re-timing signal. The control system includes a filtering and re-timing unit for receiving a radio frequency (RF) signal and outputting the re-timing signal and an un-corrected output signal, an error correction unit for receiving the un-corrected output signal and correcting an error bit according to a Reed-Solomon algorithm to generate a corrected output signal, a lock performance detector for receiving the re-timing signal and detecting the lock performance of the re-timing signal and then outputting a lock performance index, and a servo control loop for receiving the RF signal and the lock performance index and thus generating a servo control signal. When the lock performance index does not reach a threshold value, the servo control loop loads other control parameters to improve the read performance of the optical storage device.

    摘要： A focusing servo device, an optical disc recording/reproducing device and a focus-searching method are provided for making a focus of an energy beam emitted by a pick-up unit to fall in an accessible range of a data layer of a disc. The method comprises the following steps: recording the deviation of the focal point during each predetermined period when the focal point of the energy beam is fallen in the accessible range such that the optical disc recording/reproducing device is operated in a feedback control mode; determining a focus-searching range based on the recorded deviation of the focal point; and moving the focal point in the focus-searching range to make the focal point to fall in the accessible range when the focal point of the energy beam is fallen out of the accessible range such that the optical disc recording/reproducing device is operated in a focus-searching mode.
