Description

Detailed Description of the Invention

[0001]

The present invention relates to a history of use of recording media such as video tapes and magnetic disks, or
The present invention relates to a recording medium having a storage unit that stores data indicating an attribute such as whether to take it out, and a management device that manages the recording medium.

[0002]

Conventionally, in order to manage a recording medium such as a video tape and a magnetic disk, a card showing recorded contents is attached to a shell of the recording medium and filled in a ledger every time it is used.
