A technique for reducing pole tip protrusion ("PTP") in a magnetic write head
and
giant magnetoresistive ("GMR") stripe temperature in an associated read head structure
utilizing one or more internal diffuser regions. In a representative embodiment
disclosed, this may be effectuated through the appropriate placement of a relatively
highly conductive material diffuser region (e.g. gold (Au) or copper (Cu)) above
the poles, between the first pole and the coil and/or through the first pole, second
and first shields and undercoat layer to the substrate in order to conduct heat
away from the write head poles, insulating layers (e.g. photoresist) and shields.
