ABSTRACT:
A magnetic head having a head core which includes a first head core half body (22) having a winding groove (22b) at one side surface thereof, a second head core half body (23) having one side surface joined with the side surface of the first body, both bodies being fixed by mold glass (25) about a joined plane thereof via a gap spacer (24) of material having a melting point higher than the mold glass, and one end surface (20a) normal to the joined plane and shaped into an arc to become a tape sliding surface having a magnetic gap at the joined plane. The first body has a back groove (22c) formed by cutting out a part near the other end surface opposite to that on which the sliding surface (20a) is formed, and a pair of first track width regulation groove (22d) cut out of both corners of the joined plane and having a slant at a predetermined angle (DEG.sub.1) extending from a portion near the opposite end toward the sliding surface (20a) and transverse to the winding groove (22b). The second body (23) has a pair of second track width regulation grooves (23b) cut out of both corners between the joined plane and the sliding surface (20a) on a slant at a predetermined angle from the middle of the winding groove (22b) to the sliding surface. The mold glass (25) is filled into the back groove (22c) and the first and second regulation grooves for fixing the first and second bodies by solidification after cooling.
