Abstract
A method for forming a diamond-like carbon (DLC) layer on air bearing surface (ABS) of a slider, comprises steps of: providing sliders arranged in arrays, each slider having an ABS; forming a mixing layer in the ABS of the slider by depositing a first DLC layer on the ABS, the mixing layer consisting of the slider material and the first DLC layer material; removing the first DLC layer to make the mixing layer exposed; forming a second DLC layer on the mixing layer.
