Abstract

The present invention relates to a technique to realize the copying operation without any deterioration of information by simplified operation on the occasion of copying information to a plurality of recording media from a source medium. A PC module registers an MD player module and a DAT player module as one group, then produces a unique group ID to this group and notifies this group ID to the MD player module and DAT player module. On the occasion of copying information to this group from the CD player module, the PC module adds the group ID and recording instruction to the reproduction instruction for the CD player module and then transmits the data to the 1394-cable. The CD player module which has received a command starts reproducing operation and transmits again the remaining part from which the command for own device is deleted to the 1394-cable. The MD player module and DAT player module recognize by the group ID that this command is directed to own device and record the information reproduced by the CD player module depending on the recording instruction.
