The invention relates to a method for storing data on a data medium comprising a memory controller and at least one memory area, and for read access to data stored on the data medium, wherein user data and file administration data are generated by a terminal and provided for storing on the data medium connected to the terminal, and the memory controller stores the user data and the file administration data, wherein the data to be stored are stored on the data medium so that during read access the memory controller can differentiate whether the data are user data or file administration data. According to the invention, the memory controller releases all or at least particular user data only if a user is authenticated, and releases all or at least particular file administration data for read access even without authentication of a user.
