    摘要： A slider for supporting transducer elements for a data storage system including at least one pressure relief trench formed in the raised bearing proximate to a contact interface position of the slider and disc surface. The trench is sized to reduce capillary pressure of the meniscus relative to disjoining pressure of a lubricant film layer on the disc surface to limit the area or expansion of a film bridge or meniscus between the bearing surface of the slider and disc surface.

    摘要： 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.

    摘要： A scratch erasure resistant perpendicular magnetic recording medium comprises a non-magnetic substrate having a surface, and a layer stack formed over the surface and comprising: (i) at least one magnetically hard perpendicular magnetic recording layer; and (ii) at least one low shear modulus layer comprising at least one material having a shear modulus not greater than about 30 GPa. Preferably, the at least one magnetically hard perpendicular magnetic recording layer includes at least a first layer comprised of a magnetic material having a hexagonal close packed (hcp) crystal structure and preferred basal plane crystallographic orientation with c-axis perpendicular to a surface thereof.

    摘要： 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.

    摘要： A disk drive system or information handling system includes a base, a disk stack rotatably attached to the base, and an actuator assembly movably attached to the base. An actuator assembly is movably attached to the base of the disk drive. The actuator assembly moves the load springs and attached slider and transducers to various radial positions on the disk. The slider is a block of material having a leading edge, a trailing edge, a first side rail, a second side rail, a leading tapered edge and a center island. The center island is positioned near the trailing edge and includes the read and write heads or transducer. Sliders have a backside surface and an air-bearing surface. The slider also has one or more pads positioned near the edges of the first rail, the second rail, and the leading tapered edge. The pads are positioned at least a selected distance from the trailing edge. The pads are also positioned such that they are unaligned in the sliding direction. The pads are also positioned so that they are unaligned in the sliding direction when the first side rail and the second side rail form an angle with respect to a tangent at the radial position on the disk. In other words, the pads are unaligned when the slider is skewed with respect to the disk. The pads are formed using photolithography techniques.

    摘要： A disc head slider includes a slider body having a leading slider edge, a trailing slider edge, a bearing surface, a back surface, which is opposite to the bearing surface, and a length measured from the leading slider edge to the trailing slider edge. First and second discrete pads extend normally from the bearing surface. The first pad is located forward of a midpoint along the length, and the second pad is located rearward of the midpoint and forward of the slider trailing edge. A recess is formed in the back surface and has a recess floor, which defines a load point surface located between the first and second pads along the length.
