Technical Examples
  1. A process for fabricating a patterned medium including 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.
