Abstract: A head core includes a pair of core parts made of a magnetic metallic material and bonded together by (1) a gap material which is a low-melting-point crystallized glass which serves as the bonding material and (2) non-magnetic material layers provided between the glass and the gap surfaces of the core parts. The non-magnetic material layers effectively prevent reaction between the low-melting-point crystallized glass and the metallic magnetic material of the core during the bonding heat treatment. The strength of the magnetic gap, as well as dimensional precision of the same, is enhanced as compared with the conventional arrangement of the same gap size in which bonding is accomplished by a low-melting-point non-crystallizable glass, even when the bonding is executed at the same temperature. The invention remarkably improves magnetic head production yields and reliability.
