MAGNETIC HEAD

摘要

The magnetic head with read-write and erase units comprises a ferrite core made of Mn-Zn ferrite or Ni-Zn ferrite and a nonmagnetic part diffusion-bonded to the ferrite core by solid phase reaction. The interface layer thickness between the Mn-Zn ferrite core and the nonmangnetic part is 5-650 micron. The interface layer thickness between the Ni-Zn ferrite core and the nonmagnetic part is 5-520 micron.
