Abstract
A glide head assembly is associated with a support structure for use with a system for testing a moving surface to detect a presence of asperities thereon. This system includes signal processing operative to process an electronic signal generated in response to the presence of an asperity. The glide head assembly comprises a flexure adapted to be secured to the support structure and positionable in proximity to the moving surface. A slider is secured to a distal end portion of the flexure. A piezoelectric transducer is sandwiched partly between the slider and the distal end portion and preferably includes a free end portion which projects outwardly from this region to define a cantilever having a selected length and width. A test device for testing a moving surface on a rotating disk to determine a presence of asperities and a methodology for producing a glide head assembly for use with such a system are also provided.
