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： 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： In addition to a nonvolatile recording area, a host interface, a controller and an update notification part are provided with a recording medium. The controller reads and writes data from and to the recording area, and sends the data of the recording area and update information to a data processing apparatus via the host interface part. In particular, the present invention is characterized in that updated information of the update notification part is updated immediately before data of the recording area is updated. The value of the update notification part can be referred to from the data processing apparatus but cannot be updated thereby. The data processing apparatus holds update information of the update notification part, whereby it can determine whether or not data stored in the recording area has been updated by another data processing apparatus. In this way, it becomes possible to determine the validity of the cache information and also determine that of index files.
摘要翻译：除了非易失性记录区域之外，主机接口，控制器和更新通知部分还具有记录介质。控制器从记录区读取和写入数据，经由主机接口部分将记录区域的数据和更新信息发送到数据处理装置。特别地，本发明的特征在于，在更新记录区域的数据之前立即更新更新通知部分的更新信息。可以从数据处理装置参考更新通知部分的值，但是不能由此更新。数据处理装置保持更新通知部分的更新信息，从而可以确定存储在记录区域中的数据是否已被其他数据处理装置更新。以这种方式，可以确定高速缓存信息的有效性并且还确定索引文件的有效性。

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： 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.
摘要翻译：主机设备沿着预定的命令序列从命令发送单元（101a）发送命令。存储装置（2）在命令接收部（202a）中接收命令。访问确定单元（202c）确定从主机设备（1）发送的命令的顺序，并且确定只有当序列与预定序列相同时，对主机设备（1）的访问的接收才被使能。因此，通过简单的控制，可以防止主机装置破坏老版本的数据。

摘要： A host information memory is provided in a semiconductor memory card and a data write start address and a data size supplied by an access unit are stored. A free physical area generation section determines whether or not to perform erasing of an invalid block of a nonvolatile memory when writing of data based on the data write start address and data size, and determines the number of blocks to be erased. When erasing, writing of data and erasing of invalid blocks are simultaneously performed with respect to different memory chips. Erase process of data, herewith, can be optimized and high speed access from the access unit to a semiconductor memory card can be realized.

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.
