Method for manufacturing magnetic media with textured CSS landing zone formed by ion implantation, and media obtained thereby

Abstract

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.
