A configuration for preventing authentication processing due to continuous use of an old authorized device certificate, and illegal use of contents is provided. An arrangement is made wherein with playback or recording processing of contents accompanying data transfer between two different devices such as a drive and a host or the like, when performing mutual authentication between devices for executing data transfer, the number of times of authentication is counted, and in the event of this reaching a predetermined upper limit value of the number of times of authentication, authentication processing is cancelled, and it is necessary to update a certificate to be applied to authentication. The present configuration eliminates contents use due to continuity of authentication processing to which an old certificate is applied, and enables prompting a user to obtain the newest certificate.

Provided is a method for easily discriminating that a disc is a blank disc that conforms to the DVD Download standards. An optical disc device is provided with a first identifying means (4) which identifies disc information written in a lead-in zone of an optical disc (1); a second identifying means (4) which identifies that there is no data recorded in the data zone of the optical disc (1); and a discriminating means (5) which discriminates that the optical disc is a blank disc that conforms to the DVD Download standards, based on output from the first identifying means and output which is outputted from the second identifying means and indicating that there is no data recorded.

In accordance with one aspect of the invention, a system is provided that includes a database configured to store data according to a first encryption protocol such as an FDE HDD protocol. The data provided to the database is encrypted according to a second encryption protocol such as an AES protocol. A user selects a desired video through a server coupled to the database. Upon payment and selection by the user, a manager provides the a first key to the database so that the first encryption may be stripped from the selected video. The server couples to a remote content key server to obtain a second key to remove the second type of encryption. The resulting decrypted digitized video may then be burned to a DVD disc for distribution to the user.

An information recording medium includes a lead-in area and a data area for storing contents information. The lead-in area includes a first lead-in information area and a second lead-in information area. The first lead-in information area corresponds to a first playback mode. The second lead-in information area corresponds to a second playback mode different from the first playback mode. The first lead-in information area has a first depth and is designed for storing lead-in information related to the contents information stored in the data area. The second lead-in information area includes pre-pits having a second depth greater than the first depth. The pre-pits represent predetermined information, such as information of copyright protection, related to the contents information stored in the data area.
