Abstract

A recording medium, and a method and apparatus for recording management information on the recording medium, are provided. According to an embodiment, there is provided a method for recording management information on a recording medium, the method comprising: determining whether recording of padding data in a recordable area of a recordable recording-range of the recording medium is performed, when the recordable recording-range is changed to be a non-recordable recording range; and recording padding indicator information indicating whether the recording of padding data is performed.

Claims

1. A method for recording management information on a recording medium, the method comprising:

determining whether recording of padding data in a recordable area of a recordable recording-range of the recording medium is performed, when the recordable recording-range is changed to be a non-recordable recording range; and

recording padding indicator information indicating whether the recording of padding data is performed,

wherein the value of the padding indicator information is determined based on the determining step.

2. The method of claim 1, wherein the recording of padding data is selectively performed.

3. The method of claim 1, wherein the padding data is dummy data or zero values.

4. The method of claim 1, wherein the padding data is recorded in all recordable area of the recordable recording-range.

5. The method of claim 1, wherein the padding indicator information is recorded on a management area of the recording medium.

6. The method of claim 1, wherein the padding indicator information consists of 2 bits.

7. An apparatus for recording management information on a recording medium, the apparatus comprising:

a recording/reproducing part configured to write/read data on/from the recording medium; and

a controller, operatively coupled to the recording/reproducing part, configured to determine whether recording of padding data in a recordable area of a recordable recording-range of the recording medium is performed when the recordable recording-range is changed to be a non-recordable recording range, the controller further configured to control the recording/reproducing part to record padding indicator information indicating whether the recording of padding data is performed,

wherein the value of the padding indicator information is determined based on the determining of whether recording of padding data in a recordable area of a recordable recording-range of the recording medium is performed.

8. The apparatus of claim 7, wherein the controller is configured to control the recording/reproducing part to selectively record the padding data.

9. The apparatus of claim 7, wherein the controller is configured to control the recording/reproducing part to record the padding data as dummy data or zero values.

10. The apparatus of claim 7, wherein the controller is configured to control the recording/reproducing part to record the padding data in all recordable area of the recordable recording-range.

11. The apparatus of claim 7, wherein the controller is configured to control the recording/reproducing part to record the padding indicator information on a management area of the recording medium.

12. The apparatus of claim 7, wherein the controller is configured to control the recording/reproducing part to record the padding indicator information consisting of 2 bits.

13. A method for recording management information on a recording medium, the method comprising:

recording padding data in a recordable area of a recordable recording-range of the recording medium, when the recordable recording-range is changed to be a non-recordable recording range; and

recording padding indicator information indicating whether the recording of padding data is performed,

wherein the recording of padding data is automatically performed without an external command, when the recordable recording-range is changed to be a non-recordable recording range.

14. The method of claim 13, wherein the padding data is dummy data or zero values.

15. The method of claim 13, wherein the padding indicator information consists of 2 bits.

16. An apparatus for recording management information on a recording medium, the apparatus comprising:

a pick-up unit configured to write/read data on/from the recording medium; and

a controller, operatively coupled to the pick-up unit, configured to control the pick-up unit to record padding data in a recordable area of a recordable recording-range of the recording medium when the recordable recording-range is changed to be a non-recordable recording range, the controller further configured to control the pick-up unit to record padding indicator information indicating whether the recording of padding data is performed,

wherein the controller is configured to control the pick-up unit to automatically record the padding data without an external command, when the recordable recording-range is changed to be a non-recordable recording range.

17. The apparatus of claim 16, wherein the controller is configured to control the pick-up unit to record the padding data as dummy data or zero values.

18. The apparatus of claim 16, wherein the controller is configured to control the pick-up unit to record the padding indicator information consisting of 2 bits.

19. A computer-readable medium, comprising:

a first area configured to be allocated a recordable recording-range having at least one recordable recording unit, wherein when the recordable recording-range is changed to be a non-recordable recording range, the at least one recordable recording unit is padded with padding data; and

a second area configured to be recorded with padding indicator information indicating whether the padding data is padded in the at least one recordable recording unit,

wherein the at least one recordable recording unit is selectively padded with the padding data according to an command and the value of the padding indicator information is determined based on the selective recording of the padding data.

20. The computer-readable medium of claim 19, wherein the padding data is dummy data or zero values.

21. The computer-readable medium of claim 19, wherein the first area is a data area and the second area is a management area, the data area and the management area being separately allocated respectively.

22. The computer-readable medium of claim 19, wherein the padding indicator information consists of 2 bits.
