- Optical Recording Or Reproduction (AREA)
Abstract
An optical disc on which data is recorded and/or from which data is reproduced comprises a recording area where data is recorded in at least one physical cluster, a defective area where a defect that prevents recording and/or reproduction of data is present in the recording area, and a recording end area where information indicating an end of recording is recorded before the defective area. A method for recording data on and/or reproducing data from a high density optical disc having a defective area is performed by recording data in a predetermined recording area including the defective area, and recording data indicating an end of recording before the defective area.
Claims (7)
1. A method for recording data on and/reproducing data from a high density optical disc having a defective area, the method comprising:
recording data in a predetermined recording area including the defective area;
15 and processing a linkage to occur subsequent to the defective area.
recording data in a predetermined recording area including the defective area;
15 and processing a linkage to occur subsequent to the defective area.
2. The method as claimed in claim 2, wherein the defective area is found during verification of the disc before data is recorded or during recording and/or 20 reproduction of the data.
3. The method as claimed in either claim 1 or claim 2, wherein the data is recorded in units of physical clusters.
4. The method as claimed in either claim 1 or claim 2, wherein the recording area comprises a recorded area in which data is already recorded and a blank area in which data is not recorded.
5. The method as claimed in claim 3, wherein the recording area comprises a recorded area in which data is already recorded and a blank area in which data is not recorded.
6. The method as claimed in claim 5, wherein a run-out having a guard 2 to protect data is provided subsequent to the physical cluster, and the guard 2 has 14 the same length and pattern as a guard 3 in which data indicating an end of recording is recorded.
7. The method as claimed in claim 6, wherein the guard 3 has a length of at least 300 channel bits and is formed of a continuous pattern including at least 3T
and 5T.
and 5T.
