Abstract
The present invention provides a magnetic head slider including rails formed on the medium-facing surface on the magnetic disk side for generating buoyant force so that the slider flies and moves above a magnetic disk to write or read magnetic information. In the magnetic head slider, a first carbon film having corrosion resistance is provided on the surface of the rails provided on the medium-facing surface of the slider body through an adhesive layer, protrusions formed by alternately laminating an intermediate film and a second carbon film are provided on the first carbon film, and at least the outermost second carbon film of the second carbon films, which constitute each of the protrusions, has abrasion resistance.
