    摘要： A link writing method for a recordable or rewritable compact disk includes recording a writing interruption address and enabling a succeeding writing process after the writing interruption. Enabling a succeeding writing process includes searching the linking area and enabling a start writing signal and activating a laser power. The method can link a succeeding writing area with a previously written interrupted area with sufficient accuracy to allow the data frame to be successfully processed by error correction within the host drive. The linking area may be positioned by counting the values of the interrupted block, the interrupted data frame, and the interrupted bit count or by detecting a blank area. Other techniques for positioning the linking area include detecting an unwritten area having a length greater than a maximum or writing a characteristic pattern after an interruption.

    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 digital delaying device for delaying an input signal includes a ring oscillator, a calibration unit, and at least one delay number calculation unit and delay channel. The ring oscillator includes loop-connected delay cells for outputting an oscillation clock. The calibration unit receives a reference clock and the oscillation clock and calculates a pulse number of the oscillation clock corresponding to each reference clock period. The pulse number serves as a period reference pulse number. The calculation unit receives the pulse number and a signal delay value, calculates a signal delay number corresponding to the signal delay value according to the pulse number, and outputs a selection signal. The delay channel includes a multiplexer and cascaded delay cells, which receives an input signal and generates delay signals with different delay timings. The multiplexer selects and outputs one of the delay signals as an output signal according to the selection signal.
