Patent number: 6617012Abstract: A system and method for forming servo patterns on magnetic medium is disclosed. A magnetic film coated with a layer of styrene-acrylonitrile is stamped with a nickel stamper reproducing the negative image of the stamper pattern on the styrene-acrylonitrile. Ions are then accelerated towards the surface of the styrene-acrylonitrile, which stops the ions in the areas where the styrene-acrylonitrile is thick and allows the ions to penetrate through to the magnetic layer in the areas where the styrene-acrylonitrile is thin. The ions, which penetrate through to the magnetic layer, interact with the magnetic layer altering the magnetic layer's structure reducing its coercivity (Hc) and remnant moment (Mrt). This reproduces the stamped styrene-acrylonitrile pattern on the magnetic layer. The styrene-acrylonitrile is then removed by oxygen plasma etching the surface leaving behind a patterned magnetic medium.Type: GrantFiled: March 29, 2002Date of Patent: September 9, 2003Assignee: Seagate Technology LLCInventors: HongYing Wang, Koichi Wago, Neil Deeman, Nobuo Kurataka

Patent number: 6616982Abstract: Methods are provided for the fabrication of hydrophilic coatings on hydrophobic surfaces. In one embodiment, a polyethylene oxide (PEO) coating is fabricated on the surface of a polymeric material by contacting the surface with a methacrylic acid or acrylic acid monomer. The monomer first is reacted, for example by irradiation with an electron beam, to polymerize and covalently attach the monomer to the surface, to improve the hydrophilicity of the polymeric material. A coating of PEO molecules is subsequently attached to the polymer surface by hydrogen bond complexation. The PEO coating then may be covalently grafted onto the surface, for example, by irradiation grafting with an electron beam. The covalent grafting of a coating of the methacrylic or acrylic monomers to the surface greatly improves the wettability of the surface, and facilitates the covalent or non-covalent attachment of a coating of PEO to the polymer surface.Type: GrantFiled: November 26, 2002Date of Patent: September 9, 2003Assignee: Massachusetts Institute of TechnologyInventors: Edward W. Merrill, Susan S. Allgor, Gladys C. Leung
