Abstract
A storage system slider having a trailing edge pad and method for making the same is disclosed. A trailing edge pad to provide a carbon-carbon contact between the storage medium surface and slider and by reducing the thickness of the DLC so that the magnetic spacing is reduced. A slider body is formed having a first side, a second side, a leading edge and a trailing edge, an air bearing surface is formed on the slider body and a trailing edge pad is formed at the trailing edge of the slider. The air bearing surface may also include a protective overcoat with decreased thickness over the air bearing surfaces. The decrease in thickness of the protective overcoat may correspond to an increase in a magnetic spacing caused by the addition of the trailing edge pad to the slider, or may be greater than the corresponding increase in a magnetic spacing caused by the addition of the trailing edge pad to the slider. Moreover, the forming of the protective coat may be omitted. In this case, the trailing edge pad provides the only carbon-carbon interface between the slider and the disk.
