Abstract

The write-once recording medium has a data structure for managing temporary defect management areas, TDMAs, of the recording medium, where each TDMA is for at least storing temporary defect management information. In one embodiment, the recording medium includes a TDMA access indicator, TAI, area for selectively storing data indicating which one of the TDMAs is currently in use.

Claims

1. A write-once recording medium having a data structure for managing temporary defect management areas, TDMAs, of the recording medium, each TDMA for at least storing temporary defect management information, the recording medium comprising:

a TDMA access indicator, TAI, area for selectively storing data indicating which one of the TDMAs is currently in use.

2. The recording medium of claim 1, wherein the TAI area includes at least one portion associated with a TDMA and selectively storing data indicating whether the associated TDMA has been used.

3. The recording medium of claim 1, further comprising:

TDMA0 to TDMAn for storing temporary defect management information; and

wherein

the TAI area includes a sub-area corresponding to each one of TDMA1 to TDMAn, respectively, each sub-area including data if the corresponding TDMA has been used.

4. The recording medium of claim 3, wherein the sub-area including data that corresponds to a highest numbered TDMA indicates that the highest numbered TDMA is the TDMA currently in use.

5. The recording medium of claim 4, wherein if a TDMA has been used, the corresponding sub-area includes a first temporary disc definition structure, TDDS, which is recorded in the TDMA, the TDDS including at least one pointer to information in the TDMA.

6. The recording medium of claim 4, wherein if a TDMA has been used, the corresponding sub-area includes a plurality of copies of a first temporary disc definition structure, TDDS, which is recorded in the TDMA, the TDDS including at least one pointer to information in the TDMA.

7. The recording medium of claim 4, wherein the sub-area including data that corresponds to the highest numbered TDMA further indicates that lower numbered TDMAs have been completely used.

8. The recording medium of claim 3, wherein the sub-areas corresponding to higher numbered TDMAs have smaller addresses than sub-areas corresponding to lower numbered TDMAs.

9. The recording medium of claim 3, wherein the sub-areas are clusters.

10. The recording medium of claim 9, wherein if a TDMA has been used, the corresponding cluster has a first sector storing a first temporary disc definition structure, TDDS, which is recorded in the TDMA, the TDDS including at least one pointer to information in the TDMA.

11. The recording medium of claim 10, wherein if a TDMA has been used, each sector of the corresponding cluster includes a first temporary disc definition structure, TDDS, which is recorded in the TDMA.

12. The recording medium of claim 3, wherein the sub-areas are clusters of the TDMA0.

13. The recording medium of claim 12, wherein the sub-areas corresponding to TDMAn to TDMA1 are a second to (n+1)th cluster of the TDMA0.

14. The recording medium of claim 13, wherein the TAI area includes a first cluster of the TDMA0, and the first cluster indicates whether the recording medium is closed.

15. The recording medium of claim 14, wherein the first cluster indicates that the recording medium is closed if the first cluster includes data.

16. The recording medium of claim 15, wherein if the recording medium is closed, the first cluster includes the defect data structure, DDS, recorded in a defect management area, DMA, the DDS including at least one pointer to information in the DMA.

17. The recording medium of claim 16, wherein if the recording medium is closed, a first sector of the first cluster includes the defect data structure, DDS, recorded in a defect management area, DMA.

18. The recording medium of claim 17, wherein if the recording medium is closed, each sector of the first cluster includes the defect data structure, DDS, recorded in a defect management area, DMA.

19. The recording medium of claim 1, wherein the TAI area indicates which of the TDMAs are completely used.

20. The recording medium of claim 19, wherein the TAI area indicates whether the recording medium is closed.

21. The recording medium of claim 1, wherein the TAI area indicates whether the recording medium is closed.

22. A write-once recording medium having a data structure for managing temporary defect management areas, TDMAs, of the recording medium, the recording medium comprising:

TDMA0 to TDMAn for storing management information; and

a TDMA access indicator, TAI, area including a second to (n+1)th cluster of the TDMA0, the second to (n+1)th cluster corresponding to TDMAn to TDMA1, and if one of the TDMAn to TDMA1 has been used, each sector of the corresponding second to (n+1)th cluster includes a first temporary disc definition structure, TDDS, which is recorded in the corresponding one of the TDMAn to TDMA1, the TDDS including at least one pointer to information in the corresponding one of the TDMAn to TDMA1.

23. A method of recording a data structure for managing temporary defect management areas, TDMAs, of the recording medium, each TDMA for at least storing temporary defect management information, the method comprising:

selectively recording information in a TDMA access indicator, TAI, area of the recording medium to indicate which one of the TDMAs is currently in use.

24. A method of determining a temporary defect management area, TDMA, of a recording medium currently in use, each TDMA for at least storing temporary defect management information, the method comprising:

accessing a TDMA access indicator, TAI, area of the recording medium; and

determining the TDMA currently in use based on the accessing step.

25. An apparatus for recording a data structure for managing temporary defect management areas, TDMAs, of the recording medium, each TDMA for at least storing temporary defect management information, the apparatus comprising:

a driver for driving an optical recording device to record data on the recording medium;

a controller for controlling the driver to selectively recording information in a TDMA access indicator, TAI, area of the recording medium to indicate which one of the TDMAs is currently in use.

26. An apparatus for determining a temporary defect management area, TDMA, of a recording medium currently in use, each TDMA for at least storing temporary defect management information, the apparatus comprising:

a driver for driving an optical recording device to reproduce data from the recording medium;

a controller for controlling the driver to access a TDMA access indicator, TAI, area of the recording medium, and for determining the TDMA currently in use based on the accessing.
