When binary data and metadata related to the binary data are stored into a storage medium, a metadata storage area is allocated in advance on the storage medium. Then a storage area is allocated for storing the metadata from the head of the metadata storage area, and the metadata is stored into the allocated area. On the other hand, the binary data related to the metadata is stored into a general area other than the metadata storage area. Then link information which links the metadata and the binary data is written, in correspondence with the metadata, into the metadata storage area. As all the metadata are stored in the specialized storage area, the metadata attached to the binary data can be accessed at a high speed.
