ABSTRACT:
A glide head assembly is adapted for use with a test system to detect a presence of asperities on a moving surface and includes an elongated flexure having a first end portion attached to a mounting structure and an opposite second end portion positioned in proximity to the moving surface when in operation. A slider is disposed on the second end portion and has a first surface facing the moving surface when in operation, a second surface opposite the first surface, and a sidewall extending therebetween. A piezoelectric transducer is attached to the sidewall and projects outwardly therefrom to terminate in a free distal end. The piezoelectric transducer is adapted to vibrate when contacted by an asperity, thereby to produce an electronic signal at a selected signal frequency, and is preferably formed to include a pair of spaced apart legs.
