A data recording medium on which digital data is recorded eliminates acquisition by a user of a plurality of data recording media for different applications to improve the convenience is provided. Digital data for a plurality of different applications and UIDs as identification information added for the individual applications are recorded on the same data recording medium. For example, a music CD on which data for promotion and data for a normal version are managed with different UIDs from each other is distributed as a CD for promotion. The data for promotion allow free reproduction thereof. If a user tries the music CD and wants to purchase the data for a normal version, then the user would access a server owned or managed by a record company of a distributor of the music CD to perform a charging procedure. This validates the UID with which the data for a normal version is managed, and after the UID is authenticated by the server, reproduction of the full data is permitted.
