ABSTRACT:
A method for preventing audio data recorded on a scratched portion of a compact disc from being reproduced in a compact disc player. A reference track position of the compact disc being reproduced is detected and during playback, it is determined whether a predetermined number of tracks have been advanced from the reference track position. If it is determined that the predetermined number of tracks have not been advanced from the reference position, a skip command is inserted in program data associated with the reference track position to correct the associated program data. Alternatively, if it is determined that the predetermined number of tracks have not been advanced from the reference track position, an error count is incremented by one and then compared with a predetermined reference value to check whether the incremented error count is greater than or equal to the predetermined reference value. If it is determined that the incremented error count is smaller than the predetermined reference value, the reproduction operation continues without modification. However, if it is determined that the incremented error count is greater than or equal to the predetermined reference value, the skip command is inserted in the program data associated with the reference track position to correct the associated program data.
