Abstract

PURPOSE:To reduce the processing time by applying correction processing to a line with an error flag set in the series as an object in repeating the error correction processing thereby eliminating the undesired data processing time. CONSTITUTION:In case that three error symbols e1, e2, e3 are arranged on a row l1 and three error symbols e4, e5, e6 are arranged on a row l2, a C1 error flag is set to the rows l1, l2 at the first decoding of the C1 series. Then the error symbol of columns m1, m4 is corrected at the decoding of the C2 series, the error symbol of the columns m2, m3 is corrected at the C1 decoding by using the C1 error flag and a C1 collection flag is set to the rows l1, l2 including the corrected symbol. Then the decoding of the C1 series is repeated again. In this case, the data of the rows l1, l2 with the C1 correction flag set is read out and the C1 decoding is applied only to the rows l1, l2.
