  • Patent number: 6228439
    Abstract: An apparatus for manufacturing information recording disks is disclosed. The apparatus includes a deposition chamber for providing an undercoat layer to a substrate to be treated, a deposition chamber for providing a magnetic recording layer on the substrate, a deposition chamber for providing a protective layer over the recording layer and a holding chamber for removing the resulting information recording disk upon completion of the process steps. The deposition chamber which provides the protective layer includes a system which selectively introduces heated plasma and oxygen into the interior of the deposition chamber to clean the interior surfaces of the chamber while the apparatus is in use. The heated plasma and oxygen interact with any excess protective layer material, resulting in the formation of a gas which is removed from the interior of the deposition chamber by a pumping system.
