Abstract
A burnishing tape apparatus includes pads that press the burnishing tape against the surfaces of the disk to be burnished. The pads are mounted on pad holders that are biased to press the pads against both sides of the disk. Tape guides are used to apply tension to the burnishing pad when the pads are moved away from the disk. When the pads are away from the disk tape guides hold the burnishing tape away from the pads so that the burnishing tape may be indexed without damaging or dislodging the pads. As the pads are moved into contact with the disk, the tape guides release the tension on the burnishing tape while the centering guides ensure that the burnishing tape is centered on the pads. By releasing tension on the burnishing tape, the pads are permitted to press the approximate center of the burnishing tape against the surfaces of the disk without deforming in an uncontrolled manner.
