Title: Bias magnetic field impressing method for magneto-resistance effect type magnetic head
Inventor: TERAJIMA KOKICHI
IPC: G11B5/39
Filed: 1985-10-15
Abstract: PURPOSE:To impress a correct bias magnetic field to a magneto-resistance effect element by giving a magnetic field in the element width direction of the magneto-resistance effect element by a magnet or a coil which has been provided on the outside of a core. CONSTITUTION:By permanent magnets 13a, 13b which have been provided on the outside of a core, a magnetic field in the element width direction of a magneto-resistance effect MR element 3 is given to a magnetic core.
