ABSTRACT:
Technology for sampling optical disc data are described. A first sync tag signal and a data signal are provided, and the previous first sync tag signal is saved as a second sync tag signal. Then, the value of the first sync tag signal and the second sync tag signal are determined to be true or false so as to divide the data signal. Since the neighboring sync tag signals are detected simultaneously, and the timing for sampling the data in the frame is determined according to whether the two contiguous sync tag signals are true or false, the technology can reproduce optical disk data accurately.
