ABSTRACT:
A tracking system of the present invention comprises 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 and are reset by control signals reproduced by the control head, a still pattern generator, and an adding means which adds the output signal from the counter and the output signal from the still pattern generator. The output signal of the displacing pattern generator is amplified and applied to the positionable elements. As result, the video heads mounted on the positionable elements can properly trace on a recorded video track at both a normal tape speed or at another tape speed.
