摘要： An apparatus and method for error correction in an optical disk system are described. An optical disk reproducing system calculates syndromes for each codeword to set an eraser flag during EFM demodulation. Error-correction-coding is performed using the eraser flag after completion of EFM-demodulation to reduce the access time for a data memory in error correction, thus reducing the time of error correction. The system includes a data memory for storing the EFM signals and the EFM-demodulated signals in the unit of an error correction block, an EFM demodulation and syndrome calculator for EFM-demodulating the EFM signals to output the EFM-demodulated signals to the data memory, and for calculating syndromes of the EFM-demodulated signals in the unit of the first codeword and outputting a flag indicating errors. A flag memory stores the first predetermined number of flags with respect to each of the first predetermined number of the first codewords, and an error corrector error-correction-decodes the EFM-demodulated signal stored in the data memory in the unit of an error correction block based on the flags stored in the flag memory.
