Abstract

PURPOSE: To perform mass production of C-I-C-type junction erasing magnetic heads by processing a bolck constituted from non-magnetic materials and magnetic materials to form an I-type core and a C-type core and assembling them through gap forming materials and making them into one body.
CONSTITUTION: Block C obtained by joining magnetic material 1 having a high- saturation magnetic flux density characteristic, non-magnetic materials 2 and 2 and magnetic material 4 having a low-loss characteristic into one body is sliced along dotted lines S1WS3 to obtain I-type core part 6 and C-type core forming material 7 (figures a, b and c). Next, one face of material 7 is abraded to provide concave part 8, and C-type core part 9 is formed (figur d), and then, C-type core parts 9 above are inserted in both sides of the I-type core part, where a winding is wound, through gap forming materials 12, and they are made into one body to form C-I-C- type core 14 (figures e and f). Next, the front core of core 14 is subjected to R polishing to form magnetic tape contact face 15 (figure g).
