Abstract

An information center, a terminal apparatus, a dubbing system and a dubbing method. Utilize a plurality of terminal apparatuses each owned by a user and an information center common to the terminal apparatuses. Data such as musical software can be dubbed from a recording medium such as a compact disc mounted on the terminal apparatus to other media such as a hard-disc driver employed in the terminal apparatus provided that a dubbing permission is granted by the information center. That is to say, prior to dubbing, the terminal apparatus establishes communication with the information center in order to obtain such a permission and other information related to the recording medium typically as a fee-charging service. The main function of the information center, therefore, is authentication of the user making a request for a permission to dub data. A request for such a permission made by the user may be rejected depending on the result of authentication.
