    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: Area management information is cached in a cache memory by controlling the access size when an information processor accesses the area management information in an information recording medium. When the processing content of the information processor is to retrieve an free area from the area management information, a physical management block size determined from the physical characteristics of the information recording medium is used. When the processing content is to acquire a link destination from the area management information, minimum access unit of the information recording medium is used. Consequently, overhead can be lessened when the area management information is accessed.

    摘要: An apparatus and method which can achieve high-speed data processing and long memory life and is effective to elimination of defragmentation of data, for example, is provided. A recording medium includes a logical-physical conversion table for storing correspondence of a logical address to a physical address of a block in a recording region. The recording medium has a function of replacing correspondence of a logical address to a physical address in the logical-physical conversion table, for a set of logical addresses. A data processing apparatus issues a replace command to the recording medium so that data can be rearranged on a consecutive region in the logical address space, thereby eliminating defragmentaion on the logical address space.

    摘要: A semiconductor memory card (101) has a plurality of areas (105, 106) based on different file systems. An adapter (102) includes: an area switching part (110) which a user can operates, a determination part (109) for determining the operation; and a card controller (108) for issuing a switching command for switching the area to be used for the semiconductor memory card (101) in accordance with the judgment result. When the switching command is issued in response to input from the area switching part (110), the command is interpreted by an area selector (107) of the semiconductor memory card (101) so as to select an area.

    摘要: A data processing apparatus is capable of playing back contents stored in a specified area in a recording medium. The recording medium stores content data and management information for managing the content data. When playing back a content which is managed by the management information on the recording medium but of which entity data is not present in the specified area of the recording medium, the data processing apparatus, searches, for the content, the other area of the recording medium with a search section. When the corresponding content is found, the link information selling section sets the link information (symbolic link, shortcut, etc.) on the recording medium so that the content can be accessed with the management information.
