摘要：
A method of recording and reproducing data on and from a rewritable optical disk used for recording/reproduction of data on a sector by sector basis. A dummy block or a parity subject to error detection and correction coding is additionally recorded at the rear of a data block on a sector. A defect caused by deterioration due to reiterative operation at the trail of the sector can be prevented from reaching the data block and data can be reproduced with high reliability.
