Abstract
A high resolution, low noise glide height test slider is provided to detect irregularities on a surface of a rotatable disc. A slider body is arranged to be supported by a support structure in predetermined spaced relation to the surface of the disc as it is rotating. A piezoelectric element on the slider body senses vibration forces acting on the slider body. The slider is electrically isolated from external noise sources.
