Abstract
An automatic tracking device which reproduces the biggest and clearest FM video signals onto a screen utilizes the concept that the width of the video heads are to be formed larger than the track of the video tape. The size of the video signals reproduced from these video heads are compared. From this comparison the automatic tracking device controls the video heads or tape speed to cause the video signal to be the same size without requiring a separate control track. This controlling of the video signals allows the biggest FM video signals to appear on a screen having substantially no noise.
