  • MIG magnetic head structured to minimize pseudo-gap problem
    Patent number: 5270894
    Abstract: A parallel type MIG (Metal in Gap) magnetic head includes single-crystal ferrite core halves with a thin ferromagnetic film formed on the gap-forming face of at least one of the core halves. The core halves are joined together using a glass having an Fe content in the range of 2-13 at %. The crystalline geometry of the principal magnetic path forming faces and gap forming faces of the core halves is selected to minimize the pseudo-gap problem and to improve reproduction output.
