摘要： An apparatus for identifying the address in pregroove (ADIP) of a Blu-ray disc is described. The apparatus uses a statistical scheme or distance-finding scheme to find the position of a predetermined minimum shift keying (MSK) mark or the first MSK mark, i.e. a bit sync unit, from an ADIP unit to identify data of the ADIP unit. The present invention doesn't have the error propagation effect occurring in the prior art so that the error rate for ADIP identification can be greatly reduced.

摘要： A digital sum variation (DSV) computation method and system is proposed, which is capable of determining the DSV value of a bit stream of channel-bit symbols to thereby find the optimal merge-bit symbol for insertion between each succeeding pair of the channel-bit symbols. This DSV computation method and system is characterized in the use of a Zero Digital Sum Variation (ZDSV) principle to determine the DSV. This DSV computation method and system can find the optimal merge-bit symbol for insertion between each succeeding pair of the channel-bit symbols in a more cost-effective manner with the need for a reduced amount of memory and utilizes a lookup table requiring a reduced amount of memory space for storage so that memory space can be reduced as compared to the prior art. This DSV computation method and system is therefore more advantageous to use than the prior art.

摘要： A method of recording data on an optical storage medium writes different types of data to the same area on the optical storage medium. The data to be written are successively stored in a data buffer in accordance with the sequence of the identification data of a data sector. The same area can be a lead-in area, a data area or a lead-out area. Therefore, a recording circuit can read out the data from the data buffer in accordance with the sequence of corresponding identification data and write them to corresponding tracks on the optical storage medium.

摘要： A gain calibration device and method for differential push-pull (DPP) tracking error signals in an optical storage system is provided. The gain calibration method processes the synthesized gain (SPPG) of the sub beam in the DPP tracking error signal components with respect to the main beam. The calibration theorem resides in controlling the objective lens of the pick-up head to form a lens-shift or controlling the tilt of the objective lens relative to the optical disc to make the synthesized DPP tracking error signals generate a correspondingly signal variation owing to the optical path deviation. The synthesized gain is calibrated to make the signal variation a minimum value, and the calibrated synthesized gain is the optimum value. In the method and device of the invention, the optimum synthesized gain of the sub beam is precisely computed without the assumptions of equal intensity of the two sub beams and symmetrical positions of the two sub beams with respect to the main beam, and without knowing the ratio of the pitch between the two sub beams to the track pitch.
