  • Patent number: 6466408
    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.
