項に記載の磁気記録再生装置。[Claims for Utility Model Registration] (1) It is possible to record/play back video signals of multiple channels and audio signals corresponding to each video signal of the multiple channels, and when playing back the video signals of the multiple channels. A magnetic recording/reproducing device configured such that a control means selectively switches and controls whether to derive a composite video signal synthesized by a video signal as a video output, or to select a video signal of one of the channels and derive it as a video output. A magnetic recording and reproducing apparatus characterized in that a display means is provided for displaying whether the video output is a composite video signal or a video signal of which channel according to the switching control of the control means. Device. (2) Utility model registration claim No. (1) characterized in that a selection means is provided which is controlled by the control means and derives as an audio output an audio signal corresponding to the video signal derived as the video output.
The magnetic recording and reproducing device described in 2.
