摘要： 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.

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 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 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： An arrangement and method of measuring head-media spacing modulation (HMS_Wq) removes the portion of out-of-plane motion caused by disk modes from the dynamic measurements of hard disk surface topography. Employing time-domain measurement techniques, circumferential surface topographical measurements are made for a hard disk surface. A boundary wavelength is determined, and a first partial HMS_Wq value is determined based upon measurements taken at a first disk rotational speed. A second partial HMS_Wq value is determined based upon measurements taken at a second disk rotational speed. The first and second partial HMS_Wq values are combined to provide a complete and accurate HMS_Wq value, taking advantage of the principle that the disk mode location in the spatial domain topography spectrum converted from the measured time-domain data shifts when the disk rotation speed is changed during the measurement.
