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 single crystal of Fe-Al-Si alloy havig high-magnetic permeability and specific surface azimuth. 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 by using a single crystal of Fe- Al-Si having high-magnetic-permeability and surface azimuth of surface (113) [or a surface inclining so that the properties of surface (113) will not be lost]. Because of the use of said cores, the narrow-track head whose inductance is extremely excellent can be obtained.
