ABSTRACT:
The invention relates to a control signal recording apparatus of a magnetic recording/reproducing apparatus for recording a video signal on a video track on a magnetic tape and reproducing the recorded video signal. There is provided control signal recording means for inserting a cue signal and a desired address signal as two kinds of pulse signals having different duty ratios onto a control track and the head portion of each video information. Due to this, various kinds of control signals such as cue signal, address signal, and the like can be easily recorded, erased, rewritten, and the like. Also, the address signal can be inserted after the recorded cue signal. Therefore, the editing and head search of the tape can be easily performed.
