  • Apparatus and method for disorienting magnetic particles in magnetic recording media
    Patent number: 4518627
    Abstract: An apparatus and method are provided for magnetically disorienting magnetic particles in a magnetic layer of a web coated recording medium that is designed to be used in the manufacture of flexible disks. Disorientation is achieved by subjecting the particles in a fluid pigment carried on a linear web to a rotating magnetic field that projects into the plane of the fluid layer and is rotated about an axis perpendicular to the plane. The interaction of the rotating field with the magnetic particles also has a smoothing effect on the outer surface of the magnetic layer.
