In a media processor for reading data from or writing data into a recording medium with which mutual authentication has been performed, an authentication processing section generates key information of the recording medium and obtains authentication information of attributes of data stored in the recording medium. An identification information retrieval section obtains identification information of the recording medium. A control section associates the key information, the authentication information, and the identification information with each other to store them in a storage section. In a case in which the recording medium is changed to anther one, if the identification information of the another recording medium matches the identification information stored in the storage section, the media processor uses the key information and the authentication information stored in the storage section.
