Magnetic head

摘要

Magnetic head having magnet cores of Mn-Zn ferrite or Ni-Zn ferrite and non-magnetic parts which are connected to the magnet cores, the thickness of the boundary layer between an Mn-Zn ferrite core and a non-magnetic part being from 5 mu m to 650 mu m and the thickness of the boundary layer between an Ni-Zn ferrite core and a non-magnetic part being from 5 mu m to 520 mu m. <IMAGE>
