Tracking-error correcting system in video reproducing apparatus.

摘要

A tracking-error correcting system in a rotating head magnetic recording and reproducing apparatus in which reproducing magnetic heads 1,2 can move in the direction of the axis of rotation by being mounted on a respective bimorph leaf 3,4 having piezo-electric elements. The tracking error between the reproducing head and a recorded track is detected, the reproducing head being moved automatically in a direction to attain better tracking position while the head is not in contact with the magnetic tape, so that either head's scanning trace is always maintained parallel to the recorded track. The system is thus protected from jitter or color flicker on the monitor television when the heads move in the direction of the axis of rotation.
