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
