    • An optical disk device includes a recording and reading means which performs recording of data upon, or reading of data from, an optical disk upon which are stored an ID, number of times information, and recording management information. Furthermore, when recording of data upon the optical disk has been completed, this optical disk device stores the recording management information, the number of times information, and the ID of the optical disk in a storage means in mutual correspondence. And, when the optical disk has been mounted, the recording and reading means decides whether a first situation or a second situation holds, using the ID and the number of times information of the optical disk as a key. And, if the second situation holds, the recording and reading means utilizes the recording management information in the storage means.
