A detect control device is provided that monitors a position error signal signature associated with a transducer while being operably supported by an actuator at a substantially constant fly height adjacent a storage medium to characterize the extent to which the actuator contacts an unload ramp. A method is provided for: supporting a transducer at an end of an actuator at a substantially constant fly height adjacent a storage medium; moving the actuator toward an unload ramp while maintaining the substantially constant fly height; and detecting a contacting engagement between the actuator and the unload ramp by monitoring a position error signal signature associated with the transducer.
