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 device for increasing the incident energy of an ion for coating a disc in an ion beam deposition process. The ion beam deposition process is performed in a chamber with the disc to be coated disposed therein. An ion source, having a voltage level, is introduced into the chamber for generating an ion beam for depositing ions on the disc. A bias contact is coupled to the disc and a power supply is coupled to the bias contact. The power supply applies a voltage level to the bias contact that is less than the voltage level of the ion source thereby creating a negative bias voltage between the disc and the ion source. This negative bias voltage causes the incident energy of the ion to increase. As a result, the optimal incident energy can be achieved using a lower original energy.

摘要： Disclosed is a perfluoropolyether (PFPE) lubricant comprising less than about 10 percent PFPE molecules having a molecular weight lower than about 2000 Daltons, and wherein the average molecular weight of the lubricant is greater than about 5000 Daltons. Such a lubricant comprises less than about 15 percent PFPE molecules having a moleuclar weight greater than about 10,000 Daltons. Also disclosed is a thin film magnetic disc comprising a recording surface and a PFPE lubricant in contact with the recording surface. The recording surface of such a thin film magnetic disc can be adapted to magnetically record information via an air bearing read/write head. The recording surface can be smooth. The disc can further comprise a rough-surfaced landing zone inward of the recording surface, wherein the PFPE lubricant is in contact with the landing zone. Also disclosed is a method of lubricating a thin film magnetic disc. The method can comprise applying a narrow, high molecular weight fractionated PFPE lubricant to the disc. In addition, a method of preparing a PFPE lubricant for use with a thin film magnetic disc is disclosed. The method can comprise fractionating a PFPE lubricant to include less than about 10 percent PFPE molecules having a molecular weight lower than about 2000 Daltons. The average molecular weight of such a lubricant after fractionation is greater than about 5000 Daltons.

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.
