Burnish head with ion milled aerodynamic pads configured in an elliptical pattern
A burnishing head configured to provide extremely close control of the burnishing height, to aerodynamically eject particles generated by the burnishing process from beneath the burnishing head onto the disc surface, whence they can be swept from the disc by centripetal force, and to optimize the tr...

| description | A burnishing head configured to provide extremely close control of the burnishing height, to aerodynamically eject particles generated by the burnishing process from beneath the burnishing head onto the disc surface, whence they can be swept from the disc by centripetal force, and to optimize the tribological relationship between the burnishing head and a disc being burnished. The burnishing head includes a plurality of burnishing pads arranged in an elliptical pattern, with the actual burnishing surface of the burnishing pads being either ion milled to provide a closely controlled surface texture, or lapped to a extremely smooth surface. The shape of the individual burnishing pads is also formed by the process of ion milling, and is either elliptical, or, preferably, an aerodynamic teardrop shape, which acts to aerodynamically displace generated particles from beneath the burnishing head. The burnishing surface of the burnishing pads is coated with a diamond-like coating to improve the tribological relationship between the burnishing head and the disc. |
