ABSTRACT:
Embodiments of the present invention are directed to structures of a recording head having a winged design for reducing corner stray magnetic fields. In one embodiment, the present invention comprises a magnetic recording head comprising a plurality of components. In embodiments of the present invention at least one of the plurality of components comprises a surface exposed to an air bearing surface when in operation with a recording medium. The surface exposed to the air bearing surface comprises notched edges for constraining corner stray magnetic fields associated therewith.
