Abstract:
1. A slider, comprising: a heating element coupled to a deformation region including a read-write head; a vertical control signal and a first slider power terminal provided to said heating element to create a potential difference, stimulating said heating element to increase the temperature of said deformation region, causing said deformation region to expand and alter the vertical position of said read-write head above a rotating disk surface in a hard disk drive; and an expansion chamber coupling to said deformation zone and including a heat sink plate thermally coupling to a heat sink; wherein whenever said deformation region expands in said expansion chamber and contacts said heat sink plate, heat from said deformation region is thermally transferred through said contact to said heat sink plate and out of said deformation region to said heat sink thermally coupled to said heat sink plate, lowering said temperature of said deformation region and limiting thermal pole tip protrusion of said slider.
