ABSTRACT:
An actuator arm assembly has an actuator arm and an actuator for moving the actuator arm whereby the arm assembly experiences vibrations. The actuator has a body with a recess formed therein, and a strain sensor is fitted essentially inside the recess such that the sensor generates signals correlated to the vibrations. This arrangement produces a high gain boost from the strain based sensor, making an amplifier circuit unnecessary. The sensor signals are used to damp the vibrations.
