摘要： A magnetic recording medium is formed with a distribution of low coercivity regions functioning as a transition pattern for servo information capable of being sensed by a read/write head by exposing a masked magnetic layer to ions to change the coercivity of the exposed magnetic layer without substantially affecting the topography of the magnetic layer.Embodiments of the present invention include forming a series of substantially radially extending low coercivity regions used to divide the magnetic layer into a plurality of sectors comprising substantially concentric circumferentially extending data tracks by exposing a masked magnetic layer having a high coercivity, i.e. from about 2000 Oe to about 10000 Oe, to one or more heavy atom ion bombardments of gaseous ions, e.g. argon ions, at a dose of about 1×1013 atoms/cm2 to about 9×1015 atoms/cm2 having an implantation energy of about 10 KeV to about 50 KeV.

摘要： A perfluoropolyether lubricant topcoat having at least one end-group having an epoxide ring is applied to a magnetic recording medium. Post-lubing treatment, such as ultraviolet (UV) light irradiation, of the perfluoropolyether lubricant topcoat initiates chemical bonding between the epoxide end-group and the medium surface. The lubricant of the present invention provides improved tribological performance over conventional lubricants.

摘要： A method of texturing the surface of a CSS/landing zone of a substrate for a magnetic recording medium, comprising steps of: (a) providing a disk-shaped substrate having a surface; (b) providing a patterned mask in overlying relation to the substrate surface, (c) selectively implanting ions in portions of the surface of the CSS/landing zone exposed by the patterned mask openings, whereby the height of the selectively ion-implanted portions is increased or decreased relative to the height of non-ion-implanted portions of the CSS/landing zone to form bumps or depressions, thereby providing the surface of the CSS/landing zone with a texture for reducing stiction and friction when the medium is used with a low flying height read/write transducer. Embodiments of the invention include hard disk magnetic recording media with textured CSS/landing zones produced by the inventive ion implation methodology.

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.
