  • Patent number: 6896971
    Abstract: A system and a method for coating two sides of a laminate material is disclosed in which one side of the laminate material is coated with one substance and the second side is coated with a different substance. The method described is particularly suited for applying a substance providing balancing characteristics desirable in the end product to one side of the laminate material and applying a substance providing other characteristics desirable in the end product to the other side of the laminate material. For example, a balancing substance may be applied on one side of a kraft paper sheet and a substance providing structural bonding applied to the other side, thereby eliminating the need to use a discrete balancing sheet in a laminate. The kraft sheet thus coated may be used to form a laminate panel.

  • Patent number: 6896973
    Abstract: A recording medium manufacturing method has a surface treatment process which removes contamination from a surface of a thermoplastic resin support substrate and also improves its wettability. This surface treatment process is conducted prior to forming the layer structure, which includes at least a signal recording layer, onto the surface of the thermoplastic resin support substance. The support substance is placed in an active gas atmosphere, such as ozone, followed by an inert gas atmosphere, such as nitrogen. This surface treatment process generates little deterioration in the support substrate surface.

  • Patent number: 6753078
    Abstract: A magnetic recording medium includes a highly permeable magnetic layer proximal to a recording layer. During recording, the permeable magnetic layer modifies the recording field from a recording head to produce consistently shaped recording transitions with a significant perpendicular component. The transitions are consistently shaped even though the distance between the recording head and the surface of the medium may change. Transitions so formed result in a reduction of noise from the medium surface roughness. The permeable magnetic layer further reduces noise caused by stray dipole fields.
