1. An access apparatus for performing file access on a semiconductor memory card that has a memory area comprising of a plurality of sectors, by managing one or more sectors as a cluster, and managing one or more clusters as a file, some consecutive sectors in the memory area forming a block, a block being a smallest unit on which data erasure can be performed, the block size being the power of 2 of the cluster size, the access apparatus comprising: a calculation unit operable to calculate a size of volume management information based on a number of clusters in the memory area that are to be managed, the volume management information including a master boot record, a partition table, partition boot sector information, and a file allocation table that indicates, for each file, links between clusters corresponding to the file; a reserving unit operable to reserve (1) a first area for recording the volume management information, and (2) a second area for recording user data, the first area being formed from blocks that are each larger in size than the calculated size of the volume management information, and the second area being formed from blocks following the first area; and a recording unit operable to record volume management information in the first area, and user data in the second area, wherein the recording unit is operable to record the master boot record and the partition table in a first sector of a first block in the first area and record the partition boot sector information, the file allocation table, and the predetermined number of reserved sectors which is used for padding of the first area, in order that a size of the first area is an integral multiple of the block size.
