Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus and method for head-disc interface (HDI) mode response monitoring. SOLUTION: A sensing element disposed on a rigid actuator arm is mechanically impedance matched to a head-disc interface (HDI) supported by the actuator arm to resonate at a predetermined frequency corresponding to at least one disturbance associated with the HDI.
