ABSTRACT:
Electronic damping of a deflectable videotape transducer is effected by apparatus including a deflectable support arm for supporting the transducer and deflecting it in response to an electrical deflection signal. A signal transducer generates a deflection velocity signal representative of instantaneous deflection velocity of the transducer. A feedback loop receives the deflected velocity signal, converts it to a damping signal, and applies the damping signal to the deflectable support arm to dampen vibrations therein.
