Abstract
Apparatus and related methods are described for adjusting servo gain. In an exemplary apparatus, a circuit determines a bias force error that occurs between an estimated bias force and an actual bias force on an actuator during movement by a servo motor. The circuit adjusts a servo gain in response to the bias force error, and regulates movement of the actuator by the servo motor in response to the servo gain.
