Abstract
A device for accessing data stored on a medium includes a substrate that has a transducer on a back side, a bottom side facing the disc, and a surface that protrudes from the bottom side. An insulation layer is placed on top of the surface. An electrostatic actuator electrode is placed on top of the insulation layer. The electrostatic actuator electrode faces the medium across an electrostatically charged portion of an air layer. The electrostatic actuator electrode protrudes above the surface into the electrostatically charged portion of the air layer.
