Abstract
PURPOSE: To produce a head of high strength, high recording density and high accuracy by affixing magnetic plates formed with gaps on both surfaces of a non- magnetic plate of a specified thickness to make a wafer and applying specified fabrication to the wafer.
CONSTITUTION: A non-magnetic plate such as of zinc ferrite or other of a specified thickness whose both surfaces have been polished is used as a substrate and on both surfaces thereof are bonded metallic magnetic plates IIa, IIb formed with gaps 4... of a specified width with the vapor deposition films of silicon oxide, etc. by means of organic adhesive agents or the like. Next, when coil winding holes 5... are drilled and the outside surfaces of the magnetic plates IIa, IIb are polished, the wafer for head core of a thin thickness, high strength and specified gap width is formed. When this wafer is cut to a specified shape and is subjected to polishing, core winding, etc., the magnetic head of high strength, high recording density and high accuracy may be produced.
