    摘要: A cryptographic apparatus reads, from a portable storage medium, content data and cryptographic information specifying a certain part of the content data on which cryptographic processing is to be performed, specifies the certain part in the read content data based on the read cryptographic information, and performs one of encryption and decryption on the certain part. When, for example, the content data is formed from alternating headers and variable-length data sections, the cryptographic information is a program formed from an instruction sequence. The instruction sequence has the cryptographic apparatus detect a header in the content data, read the length of the variable-length data, and perform cryptographic processing on a part of the content data between a start point and an end point, the start point being a position relative to the header position, and the end point being a value resulting from adding the length to the start point.

    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.

    摘要: An information recording device, which includes a nonvolatile memory whose areas are managed using an FAT file system and enhances the reliability of directory entries using a cyclic shift checksum, recalculates the cyclic shift checksum efficiently and performs seeking at a higher speed. A nonvolatile memory (25) of an information recording device 2 is managed using an FAT file system. In the memory, a plurality of directory entries are allocated to a single file. The device enhances the reliability of the directory entries using a cyclic shift checksum, and manages information indicating the position and the size of a storage area of file data using an extent information entry (203). The device further uses an update information entry (204) and a dummy entry (205).

    摘要: When moving image data or the like is recorded into an information recording medium, such as a flash memory, in real time, an influence of locations of free recording areas upon the recording speed is suppressed to ensure the real time performance of the data recording. In an access apparatus, there is provided an area management block control part that manages FAT1 and FAT2, which are area management information of a nonvolatile memory, on a FAT block-by-FAT block basis, and the length of the free recording area in each FAT block is calculated. Then, area management block information, in which the free recording area length in each FAT block is recorded, is generated on a RAM. A FAT block in which the free recording area length exceeds a threshold value is assigned to the data recording, thereby suppressing the number of updates of the area management information regardless of the location of the free areas. In this way, the buffer overflow can be prevented from occurring due to a high frequency of the updating of the area management information, thereby ensuring the real time performance during the data recording.
