Abstract

PURPOSE:To obtain a core for a magnetic head which exhibits excellent recording and reproducing characteristics even to high-coercive force recording medium by forming nonmagnetic layers of a prescribed thickness in the gap forming parts of the butt faces of a pair ferrite blocks. CONSTITUTION:The gap forming parts of the butt faces of a pair of the ferrite blocks 2 are etched to form rugged faces and prescribed magnetic metallic materials are deposited thereon. These blocks are joined and integrated to each other to obtain a combined and joined body 14. The prescribed nonmagnetic materials 22 are embedded into the grooves 18 for controlling track width formed in the direction orthogonal with the gaps, then the ferrite parts forming the track parts 20, the magnetic metal layers 10 and the gaps 16 are respectively exposed by cutting on the medium traveling surface. The block is cut in the section of the track width control grooves 18 in order to attain the core width T, by which the desired core 24 for the composite type magnetic head is cut out. The magnetic metallic materials are thereby made to exist only near the magnetic gap 28 and the loss of eddy current is decreased.
