  • Publication number: 20090274932
    Abstract: A sputtered metal film recording medium includes a substrate, a texture promotion layer sputtered on a first side of the substrate, a seed layer deposited on the texture promotion layer, an intermediate layer including a chromium alloy deposited on the seed layer, and a longitudinal magnetic recording layer including a cobalt alloy deposited on the intermediate layer. The texture promotion layer configures in-plane orientation of a cobalt structure in the magnetic recording layer.

  • Patent number: 7342738
    Abstract: The Invention Provides a Positioning System for a Linear Data Storage Medium, Such as magnetic tape or other data storage medium in which data is stored on parallel data tracks that extend along a length of the medium. The invention makes use of multiple actuators to control the positioning of sliders carrying read and write elements, e.g., separate sliders carrying the read and write elements, relative to the data storage medium with multiple degrees of freedom. The multiple degrees of freedom may include two or more of a vertical position, a horizontal position, a transverse position, an azimuth position, a zenith position, and a yaw position. In this manner, the invention can improve head-to-track alignment of read heads and write heads with linear data storage systems having very small track pitches, such as track pitches approximately 1 micron and especially less than 1 micron.

  • Patent number: 4803130
    Abstract: A method of mixing ferromagnetic recording media comprising the steps of:(i) coating a non-magnetic substrate material with a magnetic layer comprising Co-Cr by sputtering;(ii) after sufficient thickness built-up, introducing a gas (hydrocarbon, N.sub.2, NH.sub.3, or O.sub.2) into sputtering process to deposit a layer of Co and Cr reaction products under the following conditions:(a) film growth at least 50 Angstroms per minute; and(b) fully reacting Co and Cr wtih gas introduced;(iii) coating reactively sputtered layer with lubricant. Reactively sputtered layer promotes improved adhesion of lubricant to recording media.

  • Patent number: 4729924
    Abstract: A metallic, thin film, magnetic recording medium is disclosed wherein the surface of the metallic thin film is modified such as to promote improved adhesion with protective lubricant. A process is disclosed wherein, for example, controlled oxidation of a metallic, thin film magnetic recording medium yields a homogeneous distribution of bonding sites and wherein application of a protective lubricant (e.g., perfluoropolyether compositions) provides a recording medium exhibiting superior wear and abrasion resistance.
