A recording / reproducing circuit 16 capable of outputting a reproduction signal of the magnetic tape 14;
Is a control circuit, 18 is a recording reservation button, 19 is an operation unit,
These are operation buttons for operating the magnetic tape 11. An operation unit 20 is an operation button for operating the magnetic tape 14.

The operation of the programmed recording control section in the magnetic recording / reproducing apparatus configured as described above will be described with reference to FIG.

First, in a normal use state, when the operation section 19 is operated, the control circuit 17 converts the command code into a command code and sends it to the recording / reproducing circuit 12. Similarly, when the operation unit 20 is operated, the control circuit 17 converts the instruction code into a command code, and the recording / playback circuit 1
Sent to 5. In this manner, recording, playback, and stop operations can be arbitrarily performed on the respective magnetic tapes 11, 14.

Next, in order to perform scheduled recording, a recording start time, an end time, and the like are set by operating buttons (not shown), and then a scheduled recording button 18 is operated to start scheduled recording. Control circuit 1
When detecting that the timer recording button 18 has been operated and the timer recording has been started, the controller 7 prohibits the operation of the operation unit 20 from being accepted and sends a recording start command or a recording standby command to the recording / reproducing circuit 15. Further, the operation of the operation unit 19 is accepted, and a reproduction command or a recording command can be sent to the recording / reproducing circuit 12 according to the operation. For this reason, the video signal recorded on the magnetic tape 11 is output to the output terminal 13 even when the reserved recording is performed on the magnetic tape 14, and can be viewed on a TV or the like (not shown).

On the other hand, when the reserved recording is performed on the magnetic tape 11, the operation of the operation unit 20 is accepted, so that the video signal recorded on the magnetic tape 14 can be reproduced. Etc. (not shown).

Although the reservation recording button 18 is an operation button mounted on the VTR, the reservation recording button 18 is a remote control receiving unit, and the reservation recording button is on the remote control transmitting unit. It may be transmitted to the receiving unit.

As described above, according to the present embodiment, two magnetic recording media can be inserted into the same device, and two recording / reproducing circuits capable of recording / reproducing on each recording medium, and operating the respective recording / reproducing circuits.
