Abstract
A magnetic head according to one embodiment includes a pole piece made of a magnetic material; one or more magnetic pedestals formed over the pole piece; an insulator material formed over the pole piece adjacent the magnetic pedestals; and one or more polymer layers formed over tops of the insulator material to form a substantially planar top surface with the magnetic pedestals.
