Abstract
A contact start/stop (CSS) disk file has an improved head-disk interface which has significantly reduced static friction between the head-supporting slider and the disk. The slider has a plurality of narrow skids which project from the air-bearing surface of the slider and support the air-bearing surface off the disk when the disk file is not operating. The skids are designed to not affect the flyability of the slider and contain a protective overcoat to minimize wear at the head-disk interface.
