## 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 DS0 of the optical disc, and, in addition, records the generated DMS in a DMA mirror area of the DS1 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

The recording control apparatus according to claim 1, wherein
the basic management information contains no pointer information showing a recording location of information contained in the basic management information.

### Claim 4 (depends on 1)

The recording control apparatus according to claim 1, 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.

### Claim 5 (depends on 4)

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

### Claim 6 (depends on 4)

The recording control apparatus according to claim 4, 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.

### Claim 7 (depends on 1)
