Abstract: A magnetic head fabrication process in which a stencil layer is deposited upon a plurality of sensor layers. A photoresist mask in the desired read track width is fabricated upon the stencil layer. A reactive ion milling step is then conducted to remove the unmasked portions of the stencil layer. Where the stencil layer is composed of an organic compound, such as Duramide and/or diamond-like-carbon, a reactive ion milling step utilizing oxygen species produces a stencil of the present invention having exceptionally straight side walls with practically no undercuts.
