映像信号記録再生装置。[Claims for Utility Model Registration] Control signals with different duty ratios are recorded as index signals on a control track of a magnetic tape, and by determining the duty ratio of the control signals, the index signal is detected and the mode is set. The video signal recording and reproducing apparatus includes means for detecting the index signal in a normal playback state, means for detecting the index signal in a state other than the normal playback state, and a means for detecting the index signal in a state other than the normal playback state, and a means for detecting the index signal in a state other than the normal playback state, and a means for detecting the index signal in a state other than the normal playback state, and a means for detecting the index signal in a state other than the normal playback state, and a means for detecting the index signal in a state other than the normal playback state. A video signal recording and reproducing device characterized by comprising a memory in which a reproduction program is stored.
