Abstract

PURPOSE:To improve the error detection capability by applying error correction only when there is no incorrectable error and at least K-set of sound codes are detected in using a missing pointer so as to detect the error. CONSTITUTION:In decoding a data with an error check code by a missing pointer, the missing pointer is used to correct mis-write of the error check code. If uncorrectable error is detected, a flag representing no correction is set to stop the correction. When no uncorrectable error exists and K sets (K is a positive integer) no error codes are detected, the errors other than K sound date are corrected Thus, the error check capability is improved, pulse noise is excluded and the production of a cause deteriorating largely the quality of the reproducing signal is suppressed.
