Abstract
An apparatus for testing and processing a magnetic disk. The apparatus comprises a spindle for rotatably supporting the disk about a spindle axis; a first read and/or write head; a second read and/or write head; a gliding head; and a burnishing head, where the heads are selectively positionable along parallel axes overlying the magnetic disk; and a controller for selectively driving said heads across the magnetic disk and for selectively rotating the spindle in first and second directions.
