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： Each of memory cards (3-6) can have a different type and can be in a plurality of statuses. The memory cards are managed by a file system and data is read/written from/to the memory cards via an access device. Each of the memory cards has a recording area (31, 41, ...) in which data is recorded and managed by an independent file system, a state storage section (33, 44, ...) for storing state assigned to each of combinations of the memory card type and status and being capable of uniquely identifying the combination, and card information storage sections (32, 42, ...) the number of which is identical to the number of states the memory card can have, and which store physical characteristics concerning the recording area. The access device (1) acquires from the memory card a state enable uniquely identifying the memory card type and status. According to the state acquired, the access device (1) identifies the type and status of the memory card and executes processing in accordance with the memory card state.

摘要： A file system control section is arranged in an information processing device performing data read out and recording from/to an information recording medium. File system control information is built up in the system memory in the information processing device. The file system control section unifies a plurality of information recording media separately managed by the file system into a virtually single file system to be controlled. Moreover, when a plurality of files having an identical name are found, the file system control section manages the priority sequence indicating the information recording medium to be used with a higher priority. This priority sequence can be modified according to a request from an application program. Thus, it is possible to perform unified management of a plurality of information recording media and the application can access all of the files having the same name.

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).
