An apparatus includes a storage media having a surface coated with a lubricant, and a plurality of probes having tips contacting the lubricant, wherein the probes are coated with one of a fluorocarbon, perfluoropolyether, polytetrafluoroethylene, fluorinated ethylene propylene, polyethylene, or a hydrocarbon polymer. Measurements in accordance with the invention are relatively insensitive to process variations, and the structures using to take these measurements can be formed along with other features on an integrated circuit using standard processes. The view port is dimensioned such that a width of the port represents a predetermined amount of vane length loss. This improves electrical connectivity and thereby enhances the ability of the composition to rapidly dissipate static electric charges from its surface. A resistance heating body is formed on the heating member with the intermediary of an electric insulation layer.
