  • Reactive sputtering process for recording media
    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.

  • Metallic thin film magnetic recording medium having a hard protective layer
    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.
