Abstract
The burnishing tool has a plurality of holes in the planar surface which engages the flexible magnetic disk. Each hole contains a burnishing blade positioned at 45.degree. to the direction of motion. A manifold connects each hole to a vacuum pump which draws air into the holes causing the flexible magnetic disk to fly against the planar surface. The vacuum also removes the debris from the burnishing tool.
