    摘要： An information recording medium such as a semiconductor memory card includes a first semiconductor memory having a first recording area accessed by a relatively small access unit and storing file system management information, a second semiconductor memory having a second recording area accessed by a relatively large access unit and storing file data (file entity data), and a controller for controlling the first and second semiconductor memories. The information recording medium selects either one of recording areas of the first and second semiconductor memories depending on the data type, and writes data into the selected recording area.

    摘要： An information recording medium contains a semiconductor memory as a storage device for storing data and having plural areas to be managed by mutually independent file systems, an area information storage for storing information about size and position of each area of the semiconductor memory, a host interface for receiving a command for setting each area size of the semiconductor memory from an accessing device, and an area size setter for setting the size and position of each area of the semiconductor memory. The area size setter sets the area size of each area in the semiconductor memory based on the specified setting condition according to the command received from the accessing device.

    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： 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.
