摘要： A card information-storing portion is provided in a semiconductor memory card, and information relating to access performance such as access condition and access rate is held in the storing portion. Further, an access device acquires the held information from the semiconductor memory card to make it possible that the information can be used for control of a file system. This optimizes processing of the access device and the semiconductor memory card independent of differences in characteristics of semiconductor memory cards and management methods used, realizing high-rate access from the access device to a semiconductor memory card.

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.

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 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 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： While reproducing content stored in a recording medium, a user terminal as a data processing device downloads a related content as different content related to the reproduction target content from a content distribution server via a communication network. Immediately after the reproduction of the reproduction target content is completed, a notification prompting reproduction or purchase of the related content is provided. This permits immediate reproduction of the related content when the user purchases it, which reduces the user's waiting time, thus improving purchase motivation for the related content.

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 a 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.
摘要翻译：当信息处理器访问信息记录介质中的区域管理信息时，通过控制访问大小，将区域管理信息缓存在高速缓冲存储器中。当信息处理器的处理内容从区域管理信息中检索空闲区域时，使用从信息记录介质的物理特性确定的物理管理块大小。当处理内容从区域管理信息获取链接目的地时，使用信息记录介质的最小访问单元。因此，当访问区域管理信息时，可以减少开销。
