摘要： Ion beam-deposited, nitrogen-doped C:H films having substantially lower resistivities than undoped ion beam-deposited C:H films and suitable for use as hard, abrasion-resistant overcoat layers for magnetic recording media, such as hard disks, are formed by supplying a mixture of hydrocarbon and nitrogen gases to an ion beam generator. Nitrogen atom content of the films is controlled to within from about 5 to about 25 at. % by appropriate selection of the ratio of hydrocarbon gas flow to nitrogen gas flow. The resultant IBD i-C:HN films exhibit a reduced tendency for charge build-up thereon during hard disk operation by virtue of their lower resistivity vis-à-vis conventional a-C:H materials.

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： 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.
