ABSTRACT:
An automatic tracking system for a VTR has playback heads having widths smaller than the recorded track widths. At least two tracks are simultaneously reproduced. If mistracking occurs, the amplitude of the reproduced signal from one head decreases, while the amplitude of the signal from the other head remains constant. This is detected and used to generate a bimorph control signal to correct the tracking.
