ABSTRACT:
The recording and reproducing apparatus comprises an Small Computer System Interface (SCSI) controller, an optical disc device, a magnetic disc device, a disc controller which controls the optical disc device and the magnetic disc device, connectors which connects directly the optical disc device and the magnetic disc device, and a selector which selects one of the optical disc device and the magnetic disc device. A Copy or Verify command is carried out within the apparatus without an SCSI bus, and data are transferred through the connector. Therefore occupation of the SCSI bus and overhead of the SCSI protocol are eliminated, and the apparatus is miniaturized by common use of the SCSI controller and the disc controller.
