Abstract
An information memory apparatus for reading/writing information from/in a plurality of detachable information storage media such as optical disks includes a storage section for calculating and storing the access frequencies of data stored in the plurality of media loaded in the apparatus, an identifying section for identifying rarely accessed data of the data stored in the access frequency storage section, and centralized relocation section for performing centralized relocation of the rarely accessed data in a specific medium of the plurality of media. The limit of the storage capacity of a system based on a fixed disk (undetachable disk) unit is theoretically eliminated.
