ABSTRACT:
A magnetic head with a pair of mated core halves, the mating surfaces of the core halves being bonded with a predetermined gap length provided therebetween. The magnetic head has a gap portion where, on each of the mating surfaces of the core halves, a non-magnetic dielectric layer of SiO.sub.2 which is adjacent to the core half, a barrier layer, and a bonding glass layer are successively formed. The glass layers each associated with the corresponding core half are fusion pressure bonded together in such a manner as to form the gap portion.
