Abstract

PURPOSE:To enable stable vertical magnetizing recording over a long time with wear resistance, by providing the glass layer between the nonmagnetic substance holder holding the thin film magnetic pole from both sides of the magnetic tape running direction, the tip film surface of the magnetic pole and said holder. CONSTITUTION:Glass layers 9, 9 are bonded between the nonmagnetic substance holders 6, 6 holding the tip film surface of the thin film of magnetic pole 3 having high magnetic permeability and the pole 3 itself from both sides of running direction of the magnetic tape 1, the high permeability side members 4, 4 are bonded on both film surfaces of the magnetic pole 3 at the part other than the part bonded with the glass layers 9, 9, and they are clipped between the holders 6, 6. The energizing winding 5 is made for the tip region of the side members 4, 4. Thus, at the sliding surface between the vertical magnetiziation type head and the magnetic film 2 of the tape 1, the surface of the magnetic pole 3 is not subjected to wear due to the wear resistance of the glass layers 9, 9, allowing to increase the durability, and the linearity of the edge of the magnetic pole 3 can be kept and the vertical magnetization recording having excellent in short wavelength characteristics can be made.
