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 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： Corrosion resistant magnetic thin film media are fabricated using a CoCr magnetic layer having a stabilized protective chromium oxide film thereon. Stabilization of the protective chromium oxide film is achieved by incorporating a stabilizing element, such as Mo, V, Mn, Nb, Ni or Si, in the magnetic layer, thereby enabling elimination of the protective overcoat, e.g., C-containing protective overcoat, or forming the protective overcoat at a significantly low thickness of less than about 20 Å, e.g., up to about 1 Å. Embodiments include forming a magnetic layer comprising Co and Cr on an underlayer, and then forming a thin magnetic layer containing Co and Cr with the chromium oxide stabilizing element thereon. Embodiments further include introducing the chromium oxide stabilizing element by diffusion or ion implantation into a sputter deposited Co—Cr magnetic alloy layer.
摘要翻译：使用其上具有稳定的保护性氧化铬膜的CoCr磁性层制造耐腐蚀磁性薄膜介质。保护性氧化铬膜的稳定化是通过在磁性层中并入稳定元素如Mo，V，Mn，Nb，Ni或Si而实现的，由此能够消除保护性外涂层，例如含C的保护性外涂层，或形成保护性外涂层，其厚度小于约20埃，例如至多约。实施例包括在底层上形成包含Co和Cr的磁性层，然后在其上形成含有Co和Cr的薄的磁性层与氧化铬稳定元件。实施例还包括通过扩散或离子注入将氧化铬稳定化元件引入溅射沉积的Co-Cr磁性合金层。
