Claims

[Scope of utility model registration request]

This is a rotating two-bed type VTR that performs recording and playback by switching two heads for each vertical synchronization signal, and one head of the VTR plays back the recorded content while the other head plays video signals from the outside. A recording circuit configured to record video data, and a recording circuit that clamps the second half of one horizontal period of the signal from one head to a certain level for erasing the image when playing back the VTR, and clamps the second half of one horizontal period of the signal from the other head to a certain level for erasing the image. It is equipped with a playback circuit that clamps the first half of the image to a certain level to erase the image and plays it back, and the video from one head and the video from the other head are played back by dividing the screen into two. A VTR characterized in that it is configured to obtain a video signal that is
Device.
