Abstract: A system for controlling the load force between a magnetic transducer and a magnetic medium is disclosed. The system comprises a means for sensing the force between the magnetic transducer and the magnetic medium and for developing an electrical signal in response thereto, means for producing a reference signal, means for comparing the electrical signal and the reference signal and for developing an error signal therefrom, and actuator means responsive to the error signal for displacing the magnetic transducer relative to the magnetic medium.
