  • Patent number: 11322176
    Abstract: A method of manufacturing a magnetic recording medium forms an unfinished product including a magnetic recording layer and a protection layer that are successively formed on a substrate, and forms a lubricant layer on the protection layer of the unfinished product. The lubricant layer is formed by coating a first organic fluorine compound on the protection layer of the unfinished product, and supplying a gas, including a second organic fluorine compound, onto the protection layer of the unfinished product, and decomposing the second organic fluorine compound by Townsend discharge and ultraviolet ray irradiation. The protection layer includes carbon, and the first organic fluorine compound includes a functional group at a terminal thereof.

  • Patent number: 10888895
    Abstract: A film production method for producing a thin film on a surface of a workpiece, including the steps of: disposing the workpiece in a chamber; supplying a process gas into the chamber with the inside of the chamber being maintained at a predetermined pressure; applying a light having an energy between 3 eV and 10 eV to the surface of the workpiece to cause a photoelectron to be emitted from the surface of the workpiece; and applying an AC electric field to the surface of the workpiece, wherein the AC electric field has an electric field intensity causing a Townsend discharge to occur without generating a glow discharge plasma.
