Abstract
In a memory system using a removable recording medium and data stored in the recording medium, identifying information for identifying each recording medium from others is held in the recording medium, and when data stored in the recording medium is used, the identifying information of the recording medium is required. As a result, when a flash memory card, etc. is used, a copyright is reliably protected.
