PURPOSE:To manufacture a magnetic head free from a fear of crosstalk by forming a common side groove for restricting the width of a track in a couple of core halves, and by butting and using a couple of wafer obtained from the core half. CONSTITUTION:One-side surfaces 3 and 4 of wafers 1 and 2 of single crystal ferrite are worked into mirror surfaces, which are arranged facing the surface 6 of a jig 5. Then, the wafers are united together with a molding material 7 by using a mold 8. The molded wafers 1 and 2 are taken out of the mold and in the mirror-finished surfaces, grooves 10 for restricting track width 9 are cut. According to a usual method, a winding groove, a glass insertion groove, etc., are made and after the wafers 1 and 2 are meltstuck together while butted so that their track widths coincide with each other, a tape contact surface is rounded by being polished and the body is sliced along the broken lines to obtain magnetic head cores. |
