ABSTRACT:
An improved method of manufacturing a thin film magnetic head, which includes the steps of forming an electrically conductive material coil layer on a substrate of a magnetic material, applying onto the electrically conductive material coil layer, an insulation layer of SiO.sub.2, Si.sub.3 N.sub.4, Al.sub.2 O.sub.3 and the like by sputtering, plasma chemical vapor deposition process, etc., and further forming a coating layer of SiO.sub.2 on the insulation layer by spin-coating process for flattening the upper surface of the insulation layer.
