Abstract: The present technology relates to an information processing device and method, a recording medium, and a program, which can improve a data transfer speed. In the recording medium, a recording area is divided into a plurality of simulated zones and a set of the plurality of simulated zones composes a simulated zone group. Then, an address is set to each area in the simulated zones so that the addresses are interleaved between the simulated zones composing the simulated zone group. By interleaving the addresses between the simulated zones in this manner, a local seek operation or a rotational delay can be reduced and the data transfer speed can be improved when recording or reproducing data to the recording medium in more than one channel at the same time. The present technology can be applied to an optical disk.

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.
