    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 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： In a storage medium which has a number of areas, access to any area is controlled in accordance with whether or not access to another area is possible, and thereby, destruction of data due to malfunctioning or a wrong operation is prevented. A link control part which controls access to the second area based on the information on access to the first area is provided, and access to the second area is controlled on the basis of whether or not access to the first area is possible. Control becomes possible, such that access to the second area becomes impossible in the state where access to the first area is impossible, while access to the second area becomes possible in the case where access to the first area is possible.

    摘要： A lifetime parameter generation part 128 generates a lifetime parameter related to a lifetime of a nonvolatile memory device 110. When the remaining lifetime has become short, a mode switching part 129 switches a read-write mode of a read-write control part 124 from a rewritable mode to a write once mode and notifies an access device 100 that the mode has been switched to the write once mode. Thus, a user can easily recognize the moment when an apparatus having the built-in nonvolatile memory cannot be used, and, immediately before the lifetime is over, the mode can be automatically switched to the write once mode in which writing can be carried out only once.

    摘要： When a write command is issued, new data is written into a free physical block of a nonvolatile memory (110). Here, if data of the same logical block has been written already, the block is erased and a recording state is judged by a recording state judgment unit (126). A physical block is swapped according to the number of write processes performed. Thus, it is possible to effectively perform a swap without increasing the number of write processes in a particular area, thereby increasing the lifetime of a nonvolatile storage module.

    摘要翻译： 当发出写命令时，将新数据写入非易失性存储器（110）的空闲物理块。 这里，如果已经写入了相同的逻辑块的数据，则该块被擦除，并且由记录状态判断单元判断记录状态（126）。 一个物理块根据执行的写入处理次数进行交换。 因此，可以在不增加特定区域中的写入处理的数量的情况下有效地执行交换，从而增加非易失性存储模块的寿命。
