An embodiment of the invention is a slider with a lift pad and a thermal
protrusion pad in which the heads are located. The lift pad is located
immediately in front of the thermal protrusion pad and is designed to
achieve the flying characteristics needed for normal operation of the
disk drive. The thermal protrusion pad includes a heater which is used to
protrude the pad for burnishing-on-demand and/or for thermal fly-height
control. The thermal protrusion pad is designed to generate very little
lift so that protruding the thermal protrusion pad does not significantly
increase the lift experienced by the slider. An alternative embodiment
uses two overcoat thicknesses on the ABS surface with the thermal
protrusion pad having a thin overcoat and the lift pad having a thicker
overcoat.
