Write once type recording medium, recording device and recording method for write once type recording medium, and reproduction device and reproduction method for write once type recording medium

Abstract

On a write-once-type recording medium 10, there are provided: a definite defect management area 13 to definitely record therein defect management information; and a plurality of temporary defect management areas 14A, 14B, and 14C to temporarily record therein the defect management information. If the recording medium 10 is not yet finalized, every time the defect management information is updated, the updated defect management information is recorded into any one of the plurality of temporary defect management areas. Moreover, a status information recording area 15 is provided on the recording medium 10, and status information for indicating the temporary defect management area in which there is the defect management information recorded at last is recorded into the status information recording area 15. By referring to the status information, it is possible to quickly specify the defect management information recorded at last.

Description

technical field [0001] The present invention relates to a write-once recording medium, a recording device and a recording method for recording recording data on the write-once recording medium, and a method for recording recording data recorded on the write-once recording medium. A playback device and playback method for playback. Background technique [0002] As a technique that can improve the reliability of recording and reading recording data on high-density recording media such as optical disks, magnetic disks, and magneto-optical disks, there is defect management. That is, when there is a scratch or dust or wear on the recording medium (which is collectively referred to as a "defect"), the data to be recorded or recorded at the defective position is recorded in another area of ​​the recording medium (which is collectively referred to as "defect"). referred to as the "spare area"). As described above, by evacuating the recorded data that may be incomplete or imperfect...
