ABSTRACT:
A reproduction method for reproducing BCA data for optical discs using the defect signal. The reproduction method for reproducing BCA data includes the steps of: generating a defect signal as a BCA signal by detecting an RF signal of the BCA; generating a BCA data bit stream by sampling the BCA signal according to a sampling clock; and decoding the BCA data bit stream to generate BCA data. Because the defect signal is utilized as the BCA signal of the invention, no additional BCA signal extracting device is needed.
