Abstract
A skewed burnishing head arrangement is provided for burnishing the surface of a disc. The skewing of the burnishing head relative to the diameter perpendicular to a sweeping direction provides improved wiping action that catches loose particles and surface contamination, as well as performing aggressive asperity cutting and surface conditioning, while preventing particles from being embedded into a disc surface.
