Thin-film magnetic heads with a high track density of 25 tracks per 3.81 mm have been fabricated. The write current density is the same as that of the conventional sendust audio head. The head consists of a two-layer, high aspect ratio coil, formed by the reactive plasma etching method, and spin-coated PIQ varnish layers as the insulation layers to provide a smooth surface for subsequent coil layers and the Ni-Fe alloy layer.
