    摘要: The present invention relates to a method of fabricating a magnetoresistive head formed by laminating a magnetic layer and a nonmagnetic metal layer including a silver film and used for converting change in magnetic field into change of resistivity of the device. A method of fabricating a magnetoresistive head upon laminating on a substrate a plurality of magnetic layers arranged to put nonmagnetic metal layer therebetween and a bias magnetic layer formed adjacent to one of the magnetic layers to give a magnetization of the specified direction to the magnetic layer, comprising the steps of setting film thicknesses of the nonmagnetic metal layers to be formed, and forming the nonmagnetic metal layers under a condition where temperature of the substrate is held within a temperature range less than an upper limit of a film forming temperature not to cause pin holes in the nonmagnetic metal layer.

    摘要: A patterned medium on which, after forming a magnetic metal thin film as a recording layer, magnetic dots arranged in an array are formed by micro-fabricating the magnetic metal thin film, comprises the magnetic dots formed by micro-fabricating a solid state magnetic metal thin film. A process for fabricating a patterned medium comprises a dot-forming step for forming a dot array constituted by sample magnetic dots having a predetermined size such as a single domain particle size determined theoretically from the magnetic metal thin for a sample medium having a magnetic metal film formed with the initial conditions; a demagnetization step for AC-demagnetizing the dot array; a ratio measurement step for measuring the ratio of single magnetic domains by observing the magnetic pattern of each of the sample dots after the AC-demagnetization; and an adjustment step for determining conditions of the sputtering apparatus for forming a solid state magnetic metal thin film by adjusting the film-forming conditions such that the ratio of the single magnetic domains equals to or exceeds a predetermined value.
