Abstract

A method and apparatus for closing a recording range, a method and apparatus for closing a recording medium, a method and apparatus for recording management information, a method and apparatus for recording/reproducing data on/from a recording medium and a recording medium are disclosed. The method of closing a recording medium includes: determining a position in which recognition information is to be recorded; recording valid data located after the determined position into an unrecorded area before the guard area; and recording the recognition information in the determined position. It is possible to reproduce recording media having different versions with compatibility using the recording medium and the method of recording/reproducing the data on/from the recording medium and to reduce a time consumed for closing the recording medium.

Claims

1. A method of closing a recording range allocated in a user data area on a recording medium, the method comprising:

identifying a recording medium type from recording medium information of the recording medium; and

changing an unrecorded area in the recording range to a recorded area in case that the recording medium type indicates that the recorded area has a higher reflectivity than that of the unrecorded area.

2. A method of claim 1, further comprising:

recording an indicator in a management area of the recording medium, the indicator indicating that the recording range does not include the unrecorded area.

3. The method of claim 1, wherein the recording medium type is identified by a push-pull polarity defined in the recording medium information.

4. The method of claim 3, wherein the push-pull polarity of the recording medium is negative set to “

1”

.

5. The method of claim 1, wherein the recording medium type is identified by a recorded mark polarity defined in the recording medium information, wherein the recorded mark polarity is set to “

1”

.

6. The method of claim 1, wherein the unrecorded area in the recording range is optionally changed to a recorded area in case that the recording medium type indicates that the recorded area has a lower reflectivity than that of the unrecorded area.

7-10. -10. (canceled)

11. An apparatus for closing a recording range allocated in a user data area on a recording medium, the apparatus comprising:

a pickup unit configured to record/reproduce data on/from the recording medium; and

a control unit configured to control the pickup to reproduce recording medium information from the recording medium, identify a recording medium type from the recording medium information and control the pickup unit to change an unrecorded area in the recording range to a recorded area in case that the recording medium type indicates that the recorded area has a higher reflectivity than that of the unrecorded area.

49. The apparatus of claim 11, wherein the control unit is configured to control the pickup to record, into a management area of the recording medium, an indicator indicating that the recording range does not include the unrecorded area.

50. The apparatus of claim 11, wherein the control unit is configured to identify the recording medium type by a push-pull polarity defined in the recording medium information.

51. The apparatus of claim 50, wherein the control unit is configured to identify the recording medium as the recording medium type that the recorded area has a higher reflectivity than that of the unrecorded area in case that a push-pull polarity of the recording medium is set to “

1”

.

52. The apparatus of claim 11, wherein the control unit is configured to identify the recording medium as the recording medium type that the recorded area has a higher reflectivity than that of the unrecorded area in case that a recorded mark polarity defined in the recording medium information is set to “

1”

.

53. The apparatus of claim 11, wherein the control unit is configured to control the pickup to change optionally the unrecorded area in the recording range to a recorded area in case that the recording medium type indicates that the recorded area has a lower reflectivity than that of the unrecorded area.

12-48. -48. (canceled)

54. A computer-readable recording medium comprising:

recording medium information including recording medium type information indicating whether or not a recorded area of the recording medium has a higher reflectivity than that of an unrecorded area of the recording medium; and

a recording range in which all unrecorded areas has been changed into recorded areas when the recording range is closed, in case that the recording medium type information indicates that the recorded area of the recording medium has a higher reflectivity than that of the unrecorded area of the recording medium.

55. The computer-readable recording medium of claim 54, further comprising:

a management area storing therein an indicator indicating that the recording range does not include an unrecorded area.

56. The computer-readable recording medium of claim 54, wherein the recording medium type information is a push-pull polarity defined in the recording medium information.

57. The computer-readable recording medium of claim 56, wherein the push-pull polarity of the recording medium is set to “

1”

in case that the recording medium type information indicates that the recorded area of the recording medium has a higher reflectivity than that of the unrecorded area of the recording medium.

58. The computer-readable recording medium of claim 54, wherein the recording medium type information is a recorded mark polarity defined in the recording medium information, wherein the recorded mark polarity is set to “

1”

in case that the recording medium type information indicates that the recorded area of the recording medium has a higher reflectivity than that of the unrecorded area of the recording medium.

59. The computer-readable recording medium of claim 54, wherein the recording range includes an unrecorded area after the recording range is closed, in case that the recording medium type indicates that the recorded area has a lower reflectivity than that of the unrecorded area.
