ABSTRACT:
A thin-film magnetic head is provided which includes a substrate having formed thereon an upper and a lower thin-film magnetic core, a thin-film conductor coil, and a thin-film gap. An insulation layer is provided that electrically insulates the coil and the magnetic cores. The insulation layer is formed of an organic silicone resin with a ladder structure that is composed of silicon, oxygen and carbon. A resist is used as a mask to form the pattern of the insulation layer, and then the resin is removed
