  • Patent number: 9159353
    Abstract: Fabrication methods for magnetic recording media that use a plasma polish are disclosed. For one exemplary method, a film of a magnetic recording medium is deposited, and a top surface of the film is polished utilizing a plasma formed by a noble gas to smoothen the top surface of the film. A subsequent layer is then deposited onto the polished top surface of the film. A top surface of the subsequent layer has a reduced roughness by being deposited on the polished top surface of the film.

  • Patent number: 9133531
    Abstract: A high-energy treated cutter comprising a substrate having a top surface, an outer region, and an inner core and a wear resistant layer coupled to the top surface. The high-energy treatment alters the substrate's physical properties so that the inner core provides greater toughness and the outer region provides greater hardness, and greater abrasion resistance. The layer is protected prior to commencement of the treatment. In one embodiment, a cover is positioned to surround the layer and then the cutter undergoes treatment, wherein the cutter is subjected to impact forces with other cutters. In another embodiment, the cutter is positioned within a recess formed in a tray table, thereby providing protection to the layer. The cutter is secured in place via vacuum, glue, or weight. A spray nozzle applies shot material directed to the substrate of the cutter, thereby applying the impact forces to alter the substrate's properties.

  • Patent number: 9053719
    Abstract: A magnetic read transducer including a magnetoresistive sensor is described, as well as a fabrication method thereof. The magnetoresistive sensor includes a cap layer overlaying a free layer. The cap layer is situated with a first thickness to absorb boron from the free layer. The magnetoresistive sensor is annealed, and boron is diffused from the free layer and absorbed by the cap layer, improving the magnetic performance of the free layer. The cap layer thickness is then reduced to a second thickness, thereby reducing the shield-to-shield (SS) stack spacing of the magnetoresistive sensor and allowing for increased areal recording density.
