  • Magnetic thin film memory device
    Patent number: 5361226
    Abstract: A magnetic thin film memory device having information recorded in a magnetic thin film thereof by the direction of magnetization, and adapted to reproduce the recorded information on the basis of the voltage generated as a result of the change of the magnetization direction due to the extraordinary Hall effect, magnetoresistance effect or the like.A magnetic thin film memory device in which a magnetic thin film is formed of ferrimagnetic substance having perpendicular magnetic anisotropy, and producing extraordinary Hall effect in the composition of RE rich and having the minimum saturation field which enables recording in a small magnetic field and is hard to be influenced by temperatures.

  • Membrane type magnetic head
    Patent number: 5032944
    Abstract: A membrane type magnetic head comprises, between a substrate and a protecting layer, first and second magnetic layers, an insulating gap layer at least partly interposed between the first and second magnetic layers, a coil conductor layer and resin insulating layers surrounding the coil conductor layer. Stress relaxation layers are formed on the resin insulating layers.
