COMPACT DISC DECODER AND METHOD FOR CORRECTING ADDRESS ERRORS IN HEADER DATA BASED ON AN INPUT ERROR FLAG

A method for using a compact disc decoder to correct a code error in digital data read out from a compact disc includes extracting address data out of at least one sector read from the compact disc, and using an error detection circuit to read a condition of an input error flag corresponding to the address data of the sector, wherein if the condition of the input error flag indicates that the address data contains an error, then the extracting circuit extracts address data of another sector. The method also includes when the input error flag indicates that no error is present in the address data of the sector, the sector is referred to as a first sector, and the selection circuit selects address data of the first sector without referring to address data of any sectors read before the first sector.
