Title: Method of error detection and correction
Inventor: HIMENO TAKUJI
IPC: G11B20/12
Filed: 1985-03-13
Abstract: PURPOSE:To perform error checking with higher accuracy to improve correcting capability by executing error checking of respective data blocks by using not only CRC codes but error correction codes of cross-interleaving. CONSTITUTION:When the CRC error is introduced into the 17th and 19th data blocks, and a parity error is inputted into the 18th block, a flag map is obtained according to the processing procedure. When one of EE, EU and UE is present in the data block and there is one blank, the pointer is set to N so that the 13th, 14th, 22th and 23th blocks are N. However, since there is no error in effect, it is (n). The error correction is then performed, that is, the first correction for P series, the first correction for the Q series and the secured correction for the P series are performed, whereby, with the PER flag being '0', the word N(n) is treated as being safe while the pointer E and the word (n) are completely corrected. By this, there are obtained an error checking and error correcting methods with high error correcting capability are obtained.
