Abstract
A method of managing defects on a write-once optical recording medium having at least one recording layer is disclosed. The method of managing defects on the at least one recording layer comprises the steps of allocating at least one replacement area and a plurality of temporary defect management areas to the optical recording medium, wherein the temporary defect management areas are separately provided, and recording defect management information on at least one of the plurality of temporary defect management areas.
Claims33
A method of managing defects on an optical recording medium having at least one final defect management area, the method comprising the steps of:
- allocating at least one spare area to the recording medium, and at least one temporary defect management area to the spare area when a plurality of temporary defect management areas are to be separately provided;
- recording defect management information on at least one of the plurality of temporary defect management areas wherein the temporary defect management area is used until the recording medium is finalized;
- and
- recording the defect management information from the at least one temporary defect management area to the at least one final defect management area when the recording medium is finalized.
An apparatus for managing defects on an optical recording medium having at least one final defect management area, the apparatus comprising:
- means for allocating at least one spare area to the recording medium, and at least one temporary defect management area to the spare area when a plurality of temporary defect management areas are to be separately provided;
- means for recording defect management information on at least one of the plurality of temporary defect management areas, wherein the temporary defect management area is used until the recording medium is finalized;
- and
- means for recording the defect management information from the at least one temporary defect management area to the at least one final defect management area when the recording medium is finalized.
An optical recording medium comprising:
- a data area for allocating at least one spare area including at least one replacement area, and allocating at least one temporary defect management area to the spare area when a plurality of temporary defect management areas are to be separately provided, wherein the temporary defect management area is used until the recording medium is finalized;
- and
- at least one final defect management area for storing the defect management information, wherein the defect management information from the at least one temporary defect management area is recorded to the at least one final defect management area when the recording medium is finalized.
