A double-deck magnetic recording/reproducing apparatus includes first and second recording/reproducing portions for, during playback, receiving an FM video signal for a first (or second) format and a chrominance signal, and mixing an FM-modulated video signal and a converted-up chrominance signal to output a composite video signal, and, during recording, separating an input composite video signal into a video signal and a chrominance signal, FM-modulating the separated video signal, and converting down the separated chrominance signal to record the converted signal on the tape for the first (or second) format, an FM converter for receiving playback FM video signals from the first and second recording/reproducing portions and outputting a recording FM video signal in which the frequency band is converted from one format to the other format; a first switch which selectively supplies the recording FM video signal of the first recording/reproducing portion and the recording FM video signal of the FM converter to a recording head for the tape for the first format and a second switch which selectively supplies the recording FM video signal of the second recording/reproducing portion and the recording FM video signal of the FM converter to a recording head for the tape for the second format.
