<p>An apparatus which can achieve a synchronous dubbing and can record new data at a position just after data previously recorded without an unnatural gap and without using a buffer memory with large capacity. A reference signal from a cylinder servo circuit/tape transport servo circuit of a transmitter is converted into an isochronous packet. The packet is sent out from a digital interface transmitting circuit to a 1394 cable. On the reception side, an isochronous packet converter circuit restores a received isochronous packet into an original reference signal and sends it to the cylinder servo circuit/tape transport servo circuit. By so doing, the transmitter and the receiver are synchronized with each other, and it becomes possible to achieve a synchronous dubbing and to record new data at a position just after data previously recorded without an unnatural gap. Then the transmitter sends out dubbing data and the receiver receives it. The transmission reproduction processing and the reception recording processing are performed at the timing of the reference signal, so no buffer memory for timing adjustment is required. <IMAGE></p> |
