MAGNETO-RESISTANCE EFFECT TYPE MAGNETIC HEAD

PURPOSE:To prevent the Barkhausen noises of the magneto-resistance effect (MR) head which has an MR film, separating film, soft magnetic film for horizontal biasing and a vertical biasing film for monodomaining of the MR film and, the MR film and soft magnetic film of which consist of a central part and both ends. CONSTITUTION:The vertical biasing film 1 comes into direct contact with the MR film 2 at both ends and comes into direct contact with the soft magnetic film 3 as well. As a result, the magnetization directions of the MR film 2 and the soft magnetic film 3 are regulated by both ends and are propagated to the central part and, therefore, the film 2 and the film 3 are monoclomained over the entire surface, by which the Barkhausen noises are eliminated.
