METHOD FOR MANUFACTURING THIN FILM MAGNETIC HEAD

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a thin film magnetic head capable of enveloping each winding of a coil with an insulating layer leaving no gap and surely forming a flat surface on the insulating layer. SOLUTION: Resist liquid 65 is injected into gaps between the windings of the coil 45 wound around a magnetic piece 39. When the resist liquid 65 is cured, an insulating resin cured layer 46 is fixed between the wound wires. The insulating resin cured layer 46 and the windings of the coil 45 are coated with an insulating metal film 69. Then, the surface of the insulating metal film 69 is subjected to polishing treatment for flattening until the windings of the coil 45 are exposed. The gaps between the windings can be surely filled with the insulating layer, since the resist liquid having high fluidity can be penetrated into every corner. It can be avoided that the insulating resin cured layer 46 which is comparatively brittle is exposed to the polishing treatment for flattening.
