An access apparatus for performing file access on a semiconductor memory card that has a memory area that includes: a protected area that can only be accessed by a device connected to the semiconductor memory card once an authenticity of the connected device has been verified, and a user data area that can be accessed by the connected drive regardless of whether or not the authenticity of the connected device has been verified; the protected area and the user data area including a plurality of sectors, each group of 2 i consecutive sectors in the memory area forming a block (i being 0 or a positive integer), a block being a smallest unit on which data erasure can be performed, the access apparatus comprising: a calculation unit operable to calculate a size of volume management information; a reserving unit operable to reserve a first area (210, 211) used for recording the volume management information, and a second area used for recording user data, the first area (210, 211) having a data size larger than the calculated volume management information and including three or more blocks, and the second area being formed from blocks following the first area (210, 211); and a recording unit operable to record volume management information in the first area (210, 211), and user data in the second area, wherein the volume management information includes a master boot record, a partition table, partition boot sector information, a file allocation table, and a root directory entry, and the access apparatus being characterized in that: the recording unit records the master boot record and the partition table in a first sector of a first block of the first area (210, 211), records the root directory entry in a last block of the first area (210, 211), and records the partition boot sector information and the file allocation table in one or more consecutive blocks immediately before the last block of the first area (210, 211). a protected area that can only be accessed by a device connected to the semiconductor memory card once an authenticity of the connected device has been verified, and a user data area that can be accessed by the connected drive regardless of whether or not the authenticity of the connected device has been verified;
