Abstract
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).
