Abstract:
Q- or P-sequence error correction is suitable for correcting errors of data stored in a CD-ROM. Errors of data are corrected using a 2-word parity code added to the data and input pointers that have been set for the words that are presumed to be subjected to errors. Output pointers are set for respective words of data which are presumed not to be error-corrected completely.
