Abstract

It is possible to provide an information storage medium capable of highly reliable defect management even when the medium's resistance to overwriting is relatively low. The information storage medium includes: a defect management area (DMA) in which defect management information on the replacement process is recorded, a spare area in which defect management information on the defect management area (DMA) is recorded, and a spare area in which defect management information for managing use is recorded. The region of the DMA manager for the replacement process.

Description

technical field [0001] The present invention relates to an information storage medium (or an information recording medium), an information recording method and apparatus using the medium, and an information reproducing method and apparatus using the medium. Background technique [0002] Such information storage media include optical discs called DVDs (Digital Versatile Discs). Existing DVD standards include read-only DVD-ROM standard, recordable DVD-R standard, (about 1000 times) rewritable DVD-RW standard, (more than 10000 times) rewritable DVD-RAM standard. [0003] The ECC block in the existing DVD has a single product code structure (see Patent Document 1). [0004] In recent years, various methods of realizing higher recording density on such optical discs have been proposed. Using the ECC block structure in the existing DVD standard without any modification makes the burst length of the allowable error shorter than that in the existing DVD due to the increase of the ...
