  • Magnetic head with anisotropy in plane of core ports
    Patent number: 4685012
    Abstract: A magnetic head having a core of a magnetizable material around a part of which a coil is provided. A transducing gap is formed between two core parts of a magnetically anisotropic, amorphous ferromagnetic metal. The core parts of a magnetically anisotropic, amorphous ferromagnetic material have a magnetic anisotropy direction induced by a thermal treatment in a magnetic field which is in the plane of the core parts and encloses an angle .alpha. with the direction in which magnetic flux traverses the core parts during operation. .alpha. preferably is equial to 90.degree.. By these means an increased permeability in the MHz range is reached in combination with a minimum loss component.
