ABSTRACT:
The induction coil of the magnetic head of the present invention is fabricated in a patterned electrical insulation material, preferably utilizing reactive ion etch (RIE) techniques. The electrical insulation material is particularly patterned such that it is formed away from the ABS surface and in the location of the induction coil. A fill layer is deposited around the patterned electrical insulation material layer, such that the fill layer is disposed at the ABS surface. In a preferred embodiment, the patterned electrical insulation material is initially fabricated from hard baked photoresist and subsequent to the deposition of the fill layer the hard baked photoresist material is removed and replaced by SiO2. The SiO2is thereby located away from the ABS surface and the induction coil is subsequently fabricated within the SiO2material.
