Abstract: A system for purchasing a personal recording media includes a first station for converting at least one data composition and a data information corresponding thereto to predetermined signals and for transmitting the signals, and a receiving device for receiving the signals and for enabling a user to sense the data composition transmitted The data information corresponding to the data composition being transmitted is selectively stored, by a predetermined operation by a user, either into a storage device of a card-type storage medium when the card-type storage medium is attached to the receiving device or into a storage device in a second station including the receiving device. A desired musical composition can be recorded into a recording medium, either at the second station or at a third station, based upon the data information stored in the card-type storage medium or in the storage device of the second station, and accounting and royalty processes are implemented.
