ABSTRACT:
A process for making a magnetic head including the steps of forming a first pole piece comprising magnetic material and depositing a gap-forming layer comprising nonmagnetic material over the first pole piece. A first patterned layer of uncrosslinked polymer is formed on the gap-forming layer. The first patterned layer is cured by electron irradiation at a temperature less than about 175 C. to crosslink the polymer. A conductive coil is formed on the cured first patterned layer and a second patterned layer of uncrosslinked polymer is formed over the conductive coil. The second patterned layer is cured by electron irradiation at a temperature less than about 175 C. to crosslink the polymer. A second pole piece layer of magnetic material is formed to complete the magnetic head.
