Abstract
A disc burnishing head includes an array of burnishing pads and a first and second side rail projecting from a bottom surface of a slider body. The side rails each have an inside surface facing the burnishing pads and an outside surface facing outward. The outside surface of at least the first side rail is serrated. The serrations define a plurality of teeth and notches on the outside surface of the first side rail for cutting, cleaning, and conditioning defects from the surface of a disc.
