ABSTRACT:
In the disclosed automatic tracking control device, a moving element in a VTR laterally moves a pick-up head relative to a recording track on a recording medium. A first control circuit produces a control signal for controlling the moving element to cause the head to trace recording tracks on the recording medium, and a sampling circuit samples the control signal produced by the first control circuit at times approximately corresponding to the mid-point of the movement of the lateral head. A second control controls a drive for driving the recording medium on the basis of the signal sampled by the sampling circuit.
