Abstract

The present technology relates to a recording control apparatus, a recording control method, a drive controlling controller, a drive controlling method, a recording medium, and a program capable of reading information more reliably. A manager generates DMSs as management information for managing user data areas and spare areas of an optical disc. Further, the manager records the generated DMS in a DMA area of DS 0 of the optical disc, and, in addition, records the generated DMS in a DMA mirror area of the DS 1 surface of the optical disc. As described above, since DMSs as management information are recorded in the different areas of the optical disc, even if DMS cannot be read from one area, DMS can be read from the other area. The present technology is applicable to a recording and reproducing apparatus.

First claim

The invention claimed is:

1. A recording control apparatus, comprising:
a recording controller that controls recording of data in a write-once recording medium; and
a manager that controls the recording controller to record pieces of basic management information in the recording medium, the basic management information storing information on a recording range of the recording medium, the basic management information storing a counter showing the number of times of updating content of the basic management information,
wherein the basic management information contains no pointer information showing a recording location of information contained in the basic management information.

2. The recording control apparatus according to claim 1 , wherein
the recording medium includes a first surface capable of recording data and a second surface capable of recording data, and
the manager records the basic management information in the first surface and the second surface.

3. A recording control apparatus, comprising:
a recording controller that controls recording of data in a write-once recording medium; and
a manager that controls the recording controller to record pieces of basic management information in the recording medium, the basic management information storing information on a recording range of the recording medium, the basic management information storing a counter showing the number of times of updating content of the basic management information,
wherein the manager records, when the basic management information having a predetermined size cannot store the information on the recording range anymore, extended management information and new basic management information in the recording medium, the extended management information storing the information on the recording range, the information on the recording range having been stored in the basic management information, the new basic management information storing pointer information showing a recording location of the extended management information in the recording medium.

4. The recording control apparatus according to claim 3 , wherein
the manager records the new basic management information after the manager records the extended management information.

5. The recording control apparatus according to claim 3 , wherein
the counter stored in the basic management information includes a counter showing the number of times of updating content of the basic management information and a counter showing the number of times of updating content of the extended management information.

6. The recording control apparatus according to claim 1 , wherein
the pieces of basic management information are recorded in the recording medium before the recording medium is finalized.

7. A recording control method, comprising the step of:
controlling a recording controller that controls recording of data in a write-once recording medium to record pieces of basic management information in the recording medium, the basic management information storing information on a recording range of the recording medium, the basic management information storing a counter showing the number of times of updating content of the basic management information,
wherein the basic management information contains no pointer information showing a recording location of information contained in the basic management information.

8. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
controlling a recording controller that controls recording of data in a write-once recording medium to record pieces of basic management information in the recording medium, the basic management information storing information on a recording range of the recording medium, the basic management information storing a counter showing the number of times of updating content of the basic management information,
wherein the basic management information contains no pointer information showing a recording location of information contained in the basic management information.

9. A drive controlling controller, comprising:
a manager that records pieces of basic management information in a write-once recording medium, the basic management information storing information on a recording range of the recording medium, the basic management information storing a counter showing the number of times of updating content of the basic management information,
wherein the basic management information contains no pointer information showing a recording location of information contained in the basic management information.

10. A drive controlling method, comprising the step of:
recording pieces of basic management information in a write-once recording medium, the basic management information storing information on a recording range of the recording medium, the basic management information storing a counter showing the number of times of updating content of the basic management information,
wherein the basic management information contains no pointer information showing a recording location of information contained in the basic management information.

11. A write-once recording medium, comprising:
a recording range; and
management areas that record basic management information storing information on the recording range, the basic management information storing a counter showing the number of times of updating content of the basic management information,
wherein the basic management information contains no pointer information showing a recording location of information contained in the basic management information.

12. The recording medium according to claim 11 , further comprising:
a first surface capable of recording data and a second surface capable of recording data, wherein
the first surface and the second surface respectively include the management areas.

13. A write-once recording medium claim 12 , comprising:
a recording range; and
management areas that record basic management information storing information on the recording range, the basic management information storing a counter showing the number of times of updating content of the basic management information,
wherein when the basic management information having a predetermined size cannot store the information on the recording range anymore, extended management information and new basic management information are further recorded in the management areas, the extended management information storing the information on the recording range, the information on the recording range having been stored in the basic management information, the new basic management information storing pointer information showing a recording location of the extended management information in the recording medium.

14. The recording medium according to claim 13 , wherein
the new basic management information is recorded in the management areas after the extended management information is recorded in the management areas.

15. The recording medium according to claim 13 , wherein
the counter stored in the basic management information includes a counter showing the number of times of updating content of the basic management information and a counter showing the number of times of updating content of the extended management information.

16. The recording medium according to claim 11 , wherein
the basic management information is recorded in the management areas before the recording medium is finalized.

17. The recording control apparatus accor
