  • Patent number: 6124002
    Abstract: A method to manufacture magnetic recording medium including the step of subjecting the unfinished magnetic recording medium to a random orientation device prior to a drying step, to thereby remove the magnetic anisotropy of the magnetic recording medium caused by the preferential orientation of ferromagnetic fine particles along the travelling direction of the unfinished magnetic recording during the application of a magnetic coating composition onto a non-magnetic support strip. The random orientation device includes a magnet, which is oriented parallel to the plane of the non-magnetic strip and generates a set of lines of magnetic field. Each set of lines of magnetic fields are associated with only one magnet and contain both forward and backward directional magnetic fields in a direction perpendicular to the travelling direction of the unfinished magnetic recording medium. More than one magnet can be used; however, each magnet generates a separate and independent set of such lines of magnetic field.
