Claims19
A method of recording management information on a write-once optical recording medium, the recording medium including at least one temporary defect management area (TDMA) and at least one final defect management area (DMA), the method comprising:
- recording, in one of the at least one TDMA, management information produced while the recording medium is in use;
- and
- recording the latest management information included in one of the at least one TDMA, in the at least one DMA when the recording medium is to be finalized,
- wherein after the recording medium is finalized, recording of data on the recording medium is not allowed.
An apparatus for recording management information on a write-once optical recording medium, the recording medium including at least one temporary defect management area (TDMA) and at least one final defect management area (DMA), the apparatus comprising:
- means for recording, in one of the at least one TDMA, management information produced while the recording medium is in use;
- and
- means for recording the latest management information included in one of the at least one TDMA, in the at least one DMA when the recording medium is to be finalized,
- wherein after the recording medium is finalized, it is not allowed to record data on the recording medium.
A write-once optical recording medium for recording management information thereon, the recording medium comprising:
- at least one recording layer including at least one temporary defect management area (TDMA) and at least one final defect management area (DMA) for recording,
- wherein management information produced while the recording medium is in use is recorded in one of the at least one TDMA,
- the latest management information included in one of the at least one TDMA is recorded in the at least one DMA when the recording medium is finalized, and
- after the recording is finalized, recording of data on the recording medium is not allowed.
