Abstract
A glide head for detecting anomalies on a flat surface of a recording disk includes a slider having a sensing edge extending generally radially of the disk and a piezoelectric transducer element attached to one face of the slider and extending therefrom in cantilever fashion. The transducer element is of segmented shape and has a pair of opposed surfaces facing towards and away from the disk surface with spaced electrodes being provided thereon so as to provide stress readings only at specific locations on the body of the transducer element chosen to accentuate particular vibrational modes induced by anomalies on the disk surface.
