    摘要: A recording medium stores contents and contents keys to be used for encrypting the contents, in a plurality of storage formats. The storage formats include a storage format (a first format) for delivered contents acquired through a network, and a storage format (a second format) for local contents acquired by a method other than the delivery. The intrinsic storage formats of the contents to be stored in the recording medium are determined according to the kinds of the contents. The recording medium stores not only the contents and the contents keys but also original storage format information (an import flag) (851) which is information indicating the intrinsic storage formats of the contents. With reference to the original storage format information, a reproduction device selects a reproduction method in accordance with the intrinsic storage formats of the contents.

    摘要: A host device transmits a command from a command transmission unit (101a) along a predetermined command sequence. A storage device (2) receives the command in a command reception unit (202a). An access determination unit (202c) determines the sequence of the command transmitted from the host device (1) and determines that reception of the access to the host device (1) is enabled only when the sequence is identical with a predetermined sequence. Thus, with simple control, it is possible to prevent data destruction by a host device of an old version.

    摘要: An information recording device, which includes a nonvolatile memory whose areas are managed using an FAT file system and enhances the reliability of directory entries using a cyclic shift checksum, recalculates the cyclic shift checksum efficiently and performs seeking at a higher speed. A nonvolatile memory (25) of an information recording device 2 is managed using an FAT file system. In the memory, a plurality of directory entries are allocated to a single file. The device enhances the reliability of the directory entries using a cyclic shift checksum, and manages information indicating the position and the size of a storage area of file data using an extent information entry (203). The device further uses an update information entry (204) and a dummy entry (205).

    摘要: A region management method for an information recording medium capable of maintaining data interchangeability among devices and preventing malfunction when one information recording medium shared among devices different in type or number of file systems that can be interpreted by devices is provided. A recording region of the information recording medium is divided into a plurality of regions, and region information such as position and size of each region is held in the information recording medium. Different file systems are constructed in individual data recording regions. In response to a command from an information processing apparatus, accessible regions by the information processing apparatus are changed over by, for example, referring to validity flag information that indicates a presently valid region.
