[Problems to be Solved by the Invention] However, in the conventional configuration described above, only one magnetic tape can be inserted, and during scheduled recording, reception of the operation unit is prohibited to prevent the scheduled recording from being interrupted accidentally. Therefore, there was a problem in that video recorded on other magnetic tapes could not be played back during scheduled recording.

The present invention solves the above-mentioned conventional problems, and aims to provide a function that allows one magnetic tape to be freely reproduced even during scheduled recording on the other magnetic tape.

[0007]

[Means for Solving the Problems] In order to achieve this object, the magnetic recording/reproducing device of the present invention has two magnetic recording media that can be inserted into the same device, and two recording media that can be recorded and played back on each recording medium. A playback circuit, each operation unit that can operate each recording and playback circuit, a recording reservation button for scheduled recording, and a recording reservation button that accepts the recording reservation button and prohibits commands from the operation unit to one recording and playback circuit, and then records. It has a control circuit configuration that sends a command or a recording standby command, and sends a command only for the operation unit that can operate the other recording and reproducing circuit to the other recording and reproducing circuit.

[0008]

[Operation] With this configuration, even if one magnetic tape is in scheduled recording mode, the recording/reproducing circuit corresponding to the other magnetic tape can be activated by a command from the control unit that allows the operation button of the other magnetic tape to be activated. You can operate the other magnetic tape freely.
