Abstract
When information to be registered is produced with respect to a new group of recording mediums, such new information is shifted and stored successively in old storage areas of a memory. Therefore, the information can be stored in the memory on a time-series bases. The times at which the information is registered can easily be determined without relying on any counter or the like. When the registered information of the recording mediums which is stored in the memory is to be used again, registered information which is newer than the registered information to be used again is shifted successively into the old storage areas, and the registered information to be used again is transferred to a newest storage area. The registered information can be stored in the order of frequency of use, and registered information which is of higher frequency of use can be stored in a newer storage area. The remaining storage capacity of the storing areas is determined, and if the remaining storage capacity is not sufficient, registered information to be erased, of the entire registered information, is determined. Registered information which is less required to be registered can be determined, and can be erased when the storage capacity is not sufficient.
