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。

摘要： A memory controller (220) that controls the writing of data into or the reading of data from a non-volatile memory (230) includes a host interface unit (210) and a host information management unit (223). The host interface unit (210) receives an application ID identifying an application used when recording user data into the non-volatile memory (230) and a device ID identifying an external device (100) that uses the stated application. The host information management unit (223) records a host information table indicating a correspondence relationship between the application ID and the device ID into the non-volatile memory. The memory controller (220) can thus easily determine by what data processing device the data stored in a non-volatile storage device (200) attachable to/removable from the external device (100) has been updated.
摘要翻译：控制数据写入或从非易失性存储器（230）读取数据的存储器控制器（220）包括主机接口单元（210）和主机信息管理单元（223）。主机接口单元（210）接收标识在将用户数据记录到非易失性存储器（230）中时使用的应用的应用ID，以及识别使用所述应用的外部设备（100）的设备ID。主机信息管理单元（223）将指示应用程序ID和设备ID之间的对应关系的主机信息表记录到非易失性存储器中。因此，存储器控制器（220）可以容易地通过什么数据处理设备确定存储在可从外部设备（100）附加到/可移除的非易失性存储设备（200）中的数据已被更新。

摘要： In a file system such as an FAT file system, clusters are linked only in the forward direction. To perform seeks to clusters in the reverse direction, links need to be followed from the beginning side of the file data in every seeking operation. When a large amount of data is subjected to such reverse seeking, the overhead will be particularly large. A memory controller (101) for controlling data writing or reading to or from an information recording medium includes a control unit (105) that detects continuity of data in an address space of a file system managing data that is recorded into the information recording medium and a data-continuity management unit (103) that stores information about the continuity of the data as data-continuity information.
摘要翻译：在诸如FAT文件系统的文件系统中，簇仅在向前方向上链接。为了执行相反方向的集群搜索，需要在每个寻找操作中从文件数据的开始侧遵循链接。当大量数据遭受这种反向寻找时，开销将特别大。用于控制对信息记录介质的数据写入或读取的存储器控制器（101）包括：控制单元（105），其检测管理记录在信息记录介质中的数据的文件系统的地址空间中的数据的连续性;以及数据连续性管理单元（103），其将关于数据的连续性的信息存储为数据连续性信息。

摘要： The invention presents an encrypted content playback equipment capable of decryption and playback of an encrypted content by using key information when a key medium storing the key information is not inserted, an encrypted content playback method, a program, and a recording medium for storing the program.An encrypted content playback equipment 100 obtains key information 1 for a key medium 120, and stores the key information 1 in a provisional-key storage memory 102 as provisional key 1a, and obtains provisional-key usage limitation information 2 for limiting the use of provisional key 1a from the key medium 120. The encrypted content playback equipment 100 judges whether the provisional key 1a is usable or not based on the provisional-key usage limitation information 2, and if usable, plays back an encrypted content 3 by using the provisional key 1a.

摘要： An information processing device that reads out and records data from and on an information recording medium includes a file system controller. File system control information is constructed in a system memory within the information processing device, and the file system controller unifies and controls a plurality of information recording media which are managed by individual file systems into a single virtual file system. In addition, the file system controller manages a priority order that indicates an information recording medium to be utilized with priority if files having the same name exist. This priority order can be changed in response to a request from an application program. Thus, the processor can unify and manage the plurality of information recording media and, also, enables the application to access all of the files having the same name.

摘要： A system including a secure LSI 1 establishes a communication path to/from a server 3 (UD1), and receives a common key-encrypted program generated by encryption with a common key and transmitted from the server 3 (UD6 and UD7). The received common key-encrypted program is decrypted to generate a raw program, and the raw program is re-encrypted with an inherent key to newly generate an inherent key-encrypted program, which is stored in an external memory.

摘要： A file-update apparatus, which can mount a removable information recording medium storing a FAT and a directory entry that show a storage location, on the medium, of data constituting a content of a file, and which executes a plurality of update procedures to update the file, records progress information showing which of the update procedures have been executed in updating the file into an internal memory having a continuous power supply. Even if an abnormal stoppage of the update procedures caused by a power-down or the like occurs during updating of the FAT, for example, the progress and update information remain in the memory. Thus, the FAT and the like can be re-updated and inconsistencies resolved using this information, after recovering from the abnormal stoppage.

摘要： A host device (1) adds host function information indicating a function of the host device (1) to a command and transmits it to a storage device (2). The storage device (2) receives the command transmitted from the host device (1) and determines whether the function indicated by the host function information can be processed. When the function can be processed, the function is processed based on the command. When the function cannot be processed, no response is returned or error information is returned. Thus, under simple control, it is possible to prevent data destruction by a host device of an old version.
摘要翻译：主机设备（1）将指示主机设备（1）的功能的主机功能信息添加到命令中，并将其发送到存储设备（2）。存储装置（2）接收从主机装置（1）发送的命令，并且确定是否可以处理由主机功能信息指示的功能。当功能可以处理时，该功能将根据该命令进行处理。当函数无法处理时，不返回任何响应或返回错误信息。因此，在简单的控制下，可以防止主机装置破坏老版本的数据。
