ABSTRACT:
Data is stored in a cache memory, a cache HDD, high frequently accessed optical discs, or low frequently accessed optical discs, and the data is transferred between the cache memory and the cache HDD under the control of a control device which predicts the access frequency of data on the basis of the access history, transfers modified data items and only data items frequently accessed and not allocated to a high frequently accessed optical disc from the cache memory to the cache HDD, and deletes the remaining, thereby improving the use efficiency of the cache HDD.
