Abstract
A system and method for treating (e.g. polishing to remove defects) the surface of a media, such as a magnetic hard disk, while in operation, such as during dynamic electrical testing is disclosed. Further, a method for manufacturing a head for treating the surface of a media is disclosed.
Claims19
A method to affect a surface of a media comprising:
- providing physical interference between a plurality of elliptical pads of a component and said media surface as the media and the component move with respect to each other.
A method to manufacture a burnishing head comprising:
- covering, with a photo-reactive film coating, a row bar;
- directing light from a specific range of wavelengths through a mask to said film coating;
- removing, with a developer, an unexposed area of said film coating, which leaves an exposed area of said film coating as a photo-resistant surface of said row bar;
- and
- etching said row bar by ion-milling to form a burnishing surface.
