Abstract

PURPOSE:To manufacture a narrow-track magnetic head suitable to long-time VTR, etc., which uses a metallic tape, by composing the butted surface of a magnetic gap by using a signal crystal of Fe-Al-Si alloy having high-magnetic-permeability. CONSTITUTION:The magnetic head (where 4 is a winding window and 2 is a supporting body), formed by butting a couple of core bodies 1 mutually with core gap part 3, has the butted surface of the magnetic gap consisting of a signal crystal of Fe-Al-Si alloy having high-magnetic-permeability. By using the said cores, the narrow-track head can be obtained which has more stable wear resistace that in case when polycrystal is used.
