ABSTRACT OF THE DISCLOSURE A tracking system including positionable elements, rotary video heads mounted on the positionable elements, a control head, a frequency generator attached to a capstan motor, and a displacing pattern generator. The displacing pattern generator includes counters which count the pulses from the frequency generator. The pattern generator is re- set by control signals reproduced by the control head, a still pattern generator, and an adding means which adds the output signal from the counters and the output signal from the still patttern generator. The output signal of the dis- placing pattern generator is amplified and applied to the positionable element. As result, the video head mounted on the positionable element can properly trace on a recorded video track at a normal tape speed or at a different tape speed.
