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.
Claims29
A slider for accessing data stored on a disc, comprising:
- a slider substrate having a trailing side, a bottom side facing the disc, and an air bearing surface that protrudes from the bottom side;
- a read/write head on the trailing side, the read/write head accessing the data;
- a first insulation layer disposed on top of the air bearing surface;
- and
- a first electrostatic actuator electrode disposed on top of the first insulation layer and facing the disc across an electrostatically charged portion of an air bearing layer;
- the first electrostatic actuator electrode protruding above the air bearing surface into the electrostatically charged portion of the air bearing layer.
A method for manufacturing a slider for accessing data stored on a disc, comprising:
- providing a slider substrate having a trailing side, a bottom side facing the disc, and an air bearing surface that protrudes from the bottom side;
- depositing a read/write head on the trailing side;
- depositing an insulation layer on top of the air bearing surface;
- and
- depositing a first electrostatic actuator electrode on top of the first insulation layer to protrude above the air bearing surface.
