Abstract
The present invention has an object of providing a recording medium control method, a data management apparatus, and a recording medium for managing data by duplicating the data in each of a plurality of recording media. Two IC cards are loaded into a data management apparatus. In duplicating data in the two loaded IC cards, the two IC cards store their card characteristic numbers for self-identification and the card characteristic number of each other's pair IC card. If the card characteristic number of the pair IC card stored in one IC card matches the card characteristic number of the other IC card, the two IC cards are controllable.
