Latest Patents

Fisher's latest patents include an "Apparatus for recording magnetic impulses perpendicular to the surface." This invention discloses a method for recording magnetic impulses on a selectively magnetizable medium. The recording is achieved with the axes of magnetization being substantially perpendicular to the surface of the medium. This is accomplished by utilizing a recording medium that has a high magnetic permeability backing layer and an overlying coating of magnetic material with uniaxial anisotropy. Additionally, a unitary magnetic head is used for both recording and playback, positioned adjacent to one side of the recording medium.

Another significant patent is for a "Disc having substrate, intermediate layer and magnetically sensitive." This patent describes a structure and method for manufacturing a surface with improved smoothness. The process involves applying a layer of low melting point metal or glass to the substrate and elevating the composite structure to the melting point of the applied material. This results in a smooth surface with greatly improved roughness.
