Abstract
Official abstract text for this publication.
A disc drive assembly that includes a disc having a surface, a slider having an air-bearing surface (ABS) opposite the disc surface, and a voltage source for applying a voltage/potential across the disc and slider. Present on either the ABS or the disc surface is a surface treatment that provides a surface potential of at least +/−0.1 V. In some implementations the surface treatment is a self-assembled monolayer (SAM).
First claim
Opening claim text (preview).
What is claimed is: 1. A disc drive assembly comprising: a disc having a surface; a slider having an air-bearing surface (ABS) opposite the disc surface; a voltage source for applying a voltage/potential across the disc and slider; and a surface treatment on either the ABS or the disc surface, the surface treatment providing a surface potential of at least +/−0.5 V on the ABS or disc surface and a voltage/potential across the disc and slider of at least +/−0.5 V. 2. The disc drive assembly of claim 1 , wherein the surface treatment is on the ABS. 3. The disc drive assembly of claim 1 , wherein the surface treatment is on the disc surface. 4. The disc drive assembly of claim 1 , wherein the surface treatment provides a surface potential of at least +/−0.7 V. 5. The disc drive assembly of claim 1 , wherein the surface treatment is a doped DLC. 6. The disc drive assembly of claim 1 , wherein the surface treatment is a fluorinated DLC. 7. A disc drive assembly comprising: a disc having a surface; a slider having an air-bearing surface (ABS) opposite the disc surface; a voltage source for applying a voltage/potential across the disc and slider; a self-assembled monolayer (SAM) material having a surface potential of at least +/−0.1V on either the ABS or the disc surface; and a voltage/potential across the ABS and the disc surface of at least +/−0.5 V. 8. The disc drive assembly of claim 7 , wherein the SAM material is on the ABS. 9. The disc drive assembly of claim 7 , wherein the SAM material is on the disc surface. 10. The disc drive assembly of claim 7 , wherein the SAM material is a fluorinated SAM. 11. The disc drive assembly of claim 7 , wherein the SAM material is a fluorinated-silane SAM.
