ABSTRACT:
A system for compensating for shock force induced movement of a flying magnetic head which is positioned juxtaposed a rotating magnetic device. A chassis for supporting a rotating magnetic device and a flying head is mounted on shock absorbers to attenuate and delay externally imposed shock forces. An accelerometer is mounted on a fixed base of the system and receives the undelayed shock force and provides an output signal indicative of the magnitude and direction of the shock force being applied to the system. The undelayed output signal on the accelerometer is applied to transducer means which move the flying head away from or toward the magnetic device in anticipation of the shock force disturbing the gap between the flying head and the rotating magnetic device.
