    摘要: A magnetic marker for use with electronic article surveillance systems in which a very high order harmonic response is obtained with postage-stamp sized pieces of high permeability material shaped to have a narrow switching section within which flux is concentrated by larger sections on each end of the switching section, the concentrated flux being sufficient to result in a high harmonic response.

    摘要: In a flexible magnetic recording medium comprising first and second films (11) and (12) successively formed on a substrate (10), the first film comprises an alloy of nickel and iron together with a magnetization adjusting component. An amount of the magnetization adjusting component is adjusted so that the first film has saturation magnetization less than or equal to 500 e.m.u./cc. The magnetization adjusting component may be either molybdenum or a combination of molybdenum and copper. The magnetization adjusting component may be between 12 and 50% by weight in the first film. Alternatively, the magnetization adjusting component may be titanium or silicon. The alloy may be Permalloy. The substrate may be a polyester film.

    摘要: A thin film alloy disk for vertical magnetic recording has a cobalt-chromium-tantalum (CoCrTa) magnetic layer with perpendicular magnetic anisotropy deposited on an underlayer of beta-tantalum (.beta.-Ta). The .beta.-Ta layer is deposited on a suitable substrate, such as silicon, which is compatible with the formation of the beta phase of tantalum. The highly preferred orientation of the .beta.-Ta film on the substrate and the incorporation of Ta in the magnetic film results in the magnetic film having improved perpendicular magnetic anisotropy, high perpendicular coercivity and low horizontal coercivity. A nickel-iron (NiFe) layer may be deposited between the substrate and the .beta.-Ta underlayer to provide a magnetic flux return path.

    摘要: A process for the metal plating of aluminum comprising the steps of electrolytically anodizing the surface of the aluminum, immersing the anodized aluminum into an electrolytic plating solution and initiating deposition by passing a current through the solution for a time sufficient to form a layer of metal over the aluminum. The process is especially useful for the formation of aluminum storage discs where the electrolytic metal is a single layer of a ferromagnetic metal.
