Abstract
A burnishing head for burnishing the surface of magnetic or magneto-optical memory disks is described. The burnishing head comprises a plurality of curved burnishing pads symmetrically arranged on the bottom surface of the head. In one embodiment, there are thirteen circular burnishing pads symmetrically arranged on the bottom surface of a square burnishing pad in such a way that there is no dedicated leading edge of the burnishing head. The area between the curved burnishing pads is wide enough to allow the free flow of air to help the escape of debris created during burnishing. The burnishing head has no tapered leading edge. The burnishing pad flies parallel to the surface of the disk in a level manner, such that all burnishing pads are simultaneously used.
Claims24
A method of manufacturing a memory disk burnishing head, comprising:
- providing a body of material having two opposing surfaces;
- and
- ion milling a plurality of memory disk burnishing pads on one of the surfaces of the body.
A method of manufacturing a memory disk burnishing head, the method comprising:
- providing a body of material having two opposing surfaces;
- machining a plurality of memory disk burnishing pads on one surface of the body;
- and
- blending the comers and edges of the burnishing pads.
A burnishing head for burnishing a surface of a disk during which debris is generated, the burnishing head comprising:
- a body having opposing surfaces;
- a plurality of burnishing pads on one of the surfaces, the burnishing pads having a curved geometry that provides a steady air flow between burnishing pads to sweep the debris away;
- wherein said burnishing head flies over a surface of said disk.
