Latest Patents

John Leahy holds a patent for an "Apparatus and method for disorienting magnetic particles in magnetic." This invention provides a method for magnetically disorienting magnetic particles in a magnetic layer of a web coated recording medium. The technology 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. This field 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. He has 1 patent to his name.
