A magnetic head having an air bearing surface is used to reduce thermal
pole tip protrusion and recession. The magnetic head includes a substrate
and a data transducer positioned upon the substrate adjacent the air
bearing surface. The data transducer is comprised of a plurality of
metallic layers. A compensation structure is positioned adjacent to at
least one of the plurality of metallic layers, is exposed at the air
bearing surface or recessed at the ABS and extends substantially
perpendicular from the air bearing surface. The compensation structure is
formed of a material having a coefficient of thermal expansion less than
a coefficient of thermal expansion of a material forming the substrate.
