Abstract
Control of micro actuator movement is calibrated in response to a sinusoidal input signal. A response of the micro actuator to the sinusoidal input signal is measured, for example, based on measurement of a change in radial location of a transducer connected to the micro actuator responsive to the sinusoidal input signal. Control of the movement of the micro actuator is calibrated based on the measured response of the micro actuator to the sinusoidal input signal. For example, a gain of a micro actuator control loop that controls movement of the micro actuator may be regulated based on the measured change in radial location of the transducer. Related circuits and devices are also discussed.
