ABSTRACT:
A high-speed dubbing unit10for dubbing digital data from an optical disk15to a hard disk16at a high speed is connected via a public telephone line to a payment imposing unit20. A control unit13is provided for generating in its basic data generator13B basic data for imposing the payment from at least data indicative of the user identification and data indicative of the speed for recording the data read out from the optical disk15into the hard disk16and transmitting the basic data to the payment imposing unit20. The payment imposing unit20performs the imposing of the payment according to the basic data received from the control unit13and transmits data indicative of the completion of imposing the payment to the control unit13. In response to the data indicative of the completion of the payment, the control unit13directs the high-speed dubbing unit10to start recording the data read out from the optical disk15into the hard disk16.
