Abstract
PURPOSE: To facilitate miniaturigation, to decrease cross talk and to increase the characteristics, by inserting and welding the plate glass of non-magnetic substance between the magnetic effective gap of the composite magnetic head using ferrite as the magnetic head element to constitute the fixed magnetic circuit.
CONSTITUTION: After placing the blocks 11W14 machining the ferrite of oxide magnetic substance into a given form and mirror polishing the gap forming surface of them, the plate shape glass 15 is clipped to locate the erase gap 16 and the recording and reproduction gap 17, and unification is made by pressing and welding the part B,B' through the use of the rod glass 18 of 0.1W0.2mm of oxide lead glass lower in melting point than the plate glass 15. Further, along A-A', cutting is made on the track width. Thus, the composite head having the magnetic core pieces 1W4, erase head 5, and recording and reproduction head 6, welded with the glass 7 separated with the glass plate 8, and wound with the coils 9 and 10 is manufactured.
