    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.

    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 semiconductor recording medium holds an open flag showing presence or absence of consistency between content data stored in a data storage section and file system management information, in a system region not directly accessible from a host device. Upon receipt of a write request or erase request to the data storage section from the host device, the semiconductor recording medium automatically updates the open flag to “ON” (value showing possibility of inconsistency). When actual consistency is verified, the host device requests the recording medium to set the open flag to “OFF” (value showing presence of consistency). When mounting, the host device refers to the open flag with a special command to judge necessity for error check process.

    摘要: Provided is a method that, in the case of managing areas of a non-volatile memory of an information recording module by a file system, increases the speed of processing for writing file data and file system management information, and furthermore prevents a decrease in the rewriting lifetime of the non-volatile memory. The information recording module (2) is provided with a page cache control unit (217) that stores page cache information (224) in the non-volatile memory (22) of the information recording module (2) and performs control such that a specific physical block is used as a cache when writing small-sized data. Also, an access module (1) is provided with a page cache information setting unit (104) that sets information necessary for page cache control in the information recording module (2). The combination of the access module (1) and the information recording module (2) prevents the execution of needless saving process with use of page caching when writing small-sized data, thereby increasing the speed of writing processing.

    摘要: An access device 1 internally includes a logical-physical empty capacity management part 16 for obtaining information of a remaining capacity on a write once memory from a write once recording device 2A. In addition, the write once recording device 2A internally includes a physical empty capacity management part 27 for managing a remaining capacity on the write once memory and notifying the access device of the capacity. Prior to recording of file data, the access device 1 can know an accurate remaining capacity of the write once recording device by: obtaining a remaining capacity of the write once memory from the write once recording device 2A; and comparing the capacity with a remaining capacity on an FAT to decide an actually-recordable remaining capacity for file data.
