  • Patent number: 10181335
    Abstract: A method and system for cleaning and/or burnishing an article. The article is operated on by a burnishing object having one more cutting edges and one or more heating surfaces. The article rotates relative to the burnishing head and the cutting edges remove asperities from the article. The heating surface can be activated and can optionally protrude from the burnishing head to further reduce roughness of the surface of the article as the article is rotating relative to the head. The cutting edges and heating surfaces can be configured in shape and size (i.e., geometry) to accommodate the article.

  • Publication number: 20130071693
    Abstract: A method of manufacturing a granular perpendicular magnetic recording medium with improved corrosion resistance comprises sequential steps of providing a non-magnetic substrate including a surface; forming a soft magnetic underlayer (SUL) over the surface; post-deposition heating the SUL; forming an intermediate layer stack over the heated SUL; and forming at least one granular, magnetically hard perpendicular magnetic recording layer over the intermediate layer stack. Heating of the SUL prior to formation of the intermediate layer stack results in formation of an intermediate layer stack with a smoother surface and a granular perpendicular recording layer with increased corrosion resistance than when SUL post-deposition heating is not performed.

  • Patent number: 7772172
    Abstract: A lubricant for improving the durability and reliability of recording media used in hard drives is disclosed. The lubricant comprises a perfluoropolyether main chain with a first end attached to a hexa(trifluoromethylphenoxy)cyclotriphosphazene, a second end attached to a bonding enhancer for enhancing bonding between the lubricant and a carbon-containing layer. The bonding enhancer of the lubricant can contain multiple hydroxyl, amide groups, 2,3-dihydroxy-1-propoxyl, acetamide, methacrylate, methyl methacrylate and glycidyl ether. Some bonding enhancers such as methacrylate, methyl methacrylate or glycidyl ether, can be further activated with ultraviolet light.
