Filed: 1987-07-29
Abstract: PURPOSE:To effectively evade the generation of Barkhausen noise by obtaining the magnetic film of a head with constitution in which a magnetic layer is remained through a nonmagnetic intermediate layer, and selecting the electric characteristic of the magnetic layer. CONSTITUTION:For the constitution of the head, a coil conductor 3 and a magnetic film 5 are obtained on a substrate 1 and a pair of magnetic layers 11 and 12, which are soft-magnetic with conductivity are remained for the magnetic film 5. The magnetic layers 11 and 12, in the direction of the axis of easy magnetization, are composed of the high magnetic permeability material of coercive force >=0.5 (Oe) and angular ratio of a hysteresis curve >=0.6. The thickness of an intermediate layer 10 is selected to, for example, 5Angstrom <=(t)<=1,000Angstrom , so that a Coulomb interaction can be dominantly generated rather than an exchange interaction between the magnetic layers 11 and 12, and the thickness can be enough ignorable as a magnetic gap. Further, the thickness of the magnetic layers 11 and 12 is made >=0.3mum, and a reactance as a magnetic path is minimumized.
