Abstract
An optical disk and a method of recording data in the optical disk are provided. When data is overwritten on a recordable and/or reproducible optical disk, the method includes performing linking in front of a physical cluster from which overwriting starts. According to the method, when overwriting is performed on a portion of an optical disk in which data has been recorded, or when overwriting is performed on a portion including a defective area, linking is performed in front of the portion on which the overwriting is performed or behind the defective area, thereby realizing reliable data recording and reproducing.
Claims64
A method of recording data on a recordable and/or reproducible optical disk when the data is overwritten, the method comprising the step of performing linking in front of a physical cluster from which overwriting starts.
A method of recording data on a recordable and/or reproducible optical disk when the data is overwritten, the method comprising the steps of:
- performing linking in front of a physical cluster from which overwriting starts when the overwriting is performed after data has been recorded in the optical disk in units of physical clusters;
- and
- when a defective area on which recording cannot be performed is included in an area on which overwriting is performed, recording a guard3 for terminating the recording in a portion in front of the defective area.
An optical disk which data can be recorded in and reproduced from, the optical disk comprising:
- a plurality of physical clusters in which data is recorded;
- and
- a plurality of run-ins and run-outs provided in front of and behind the physical clusters to allow data to be accurately recorded,
- wherein when overwriting is performed in units of physical clusters, linking is performed between a run-in and an adjacent run-out in front of a physical cluster from which the overwriting starts.
An optical disk which data can be recorded in and reproduced from, the optical disk comprising:
- a plurality of physical clusters in which data is recorded;
- a plurality of run-ins and run-outs provided in front of and behind the physical clusters to allow data to be accurately recorded;
- and
- a defective area in which a defect occurs before data is recorded or while data is being recorded,
- wherein when overwriting is performed on a partial area including the defective area and at least one physical cluster, linking is performed between a run-in and an adjacent run-out in front of the partial area on which the overwriting is performed.
