    Abstract: PROBLEM TO BE SOLVED: To provide a reproducing system for reproducing only specific information, by use of a portable recording medium.SOLUTION: A reproducing apparatus includes a reproducing unit for reproducing data for a recording medium inserted therein, a storage unit which stores permission identification information; and a control unit. The control unit detects medium identification information recorded to be non-rewritable during recording medium manufacturing process by a recording system different from that of data mainly recorded on the recording medium, from the inserted recording medium. Only when the detected medium identification information coincides with the permission identification information stored in the storage unit, the reproducing unit is permitted to reproduce data on the recording medium.

    Abstract: PROBLEM TO BE SOLVED: To increase operation efficiency of data recording and reading on a multi layer optical disk.SOLUTION: An optical disk has plural recording layers formed thereon, and each of the recording layers has several continuous recording regions formed on the basis of recording purpose. Receiving an instruction to record a data in a specified address on the optical disk, when a replacement processing occurs, a replacement processing section determines a next recording address having the shortest distance between the next recording address in a radial direction of the optical disk and the specified address in the next recording addresses in the continuous recording regions on the recording layers as a replacement target of the specified address. With this, even when a replacement processing occurs, the data is recorded in a position as closer to the specified address as possible in a radial direction and the operation efficiency is increased when recording or reading data. The art is applicable to a recording and reproducing device.
