ABSTRACT:
The present invention provides a simple apparatus for modifying at will the trajectory of heads in a rotating head magnetic recorder (for example, when the playback speed is changed) without introducing any active elements in the moving parts. Fixed electromagnets, controlled by a position sensor, control pendulum movements of the heads oscillating under centrifugal force due to their rotation.
