ABSTRACT:
In a video tape recorder, luminance and chrominance signals are recorded respectively by first and second transducer heads along separate tracks skewed to the direction of tape motion. The transducer heads are rotated during particular modes such as slow-motion or still picture reproduction, in a tape-head speed relationship different from the normal tape-head speed relationship, causing the transducer heads to traverse several tracks. A switching circuit is coupled to the transducer heads to selectively connect the outputs of the heads to an output circuit in response to a point of transition of amplitude of the output signal from the second head to cancel unwanted signal components detected by the heads during traversal across the tracks.
