Abstract
An error correction method which can reduce the capacity of and the accessing frequency to a pointer RAM to allow high speed reproduction of recorded data is disclosed. The method corrects an error of cross-interleaved data to which two error correction codes of C.sub.1 and C.sub.2 are added, and comprises the steps of producing, for each one frame upon decoding based on the error correction codes C.sub.1 and C.sub.2, an error pointer indicative of an error condition of the data, and performing error correction based on a condition of the error pointer.
