ABSTRACT:
A method of manufacturing a thin film magnetic head comprising an insulating layer provided between a core and a coil is provided. Also provided is a method for forming an inorganic insulation underlying layer and an organic insulation underlying layer on a lower core layer behind a recording region. The withstand voltage between the lower core layer and the coil layer can be improved because a coil is formed on the organic insulation underlying layer with an inorganic insulation layer disposed on the organic insulation layer.
