ABSTRACT:
A magnetic head slider and a method of manufacturing the same. At a leading side of a slider substrate, a shock absorbing layer is provided which has a hardness lower than a hardness of the slider substrate, and a projecting portion is provided on a surface of the shock absorbing layer. If an external force is applied to the slider substrate and the leading side of the slider substrate becomes closer to a magnetic disk, only the projecting portions contact with the magnetic disk. A height of a convex portion and a depth of a concave portion, which are generated on the surface of the magnetic disk, can be decreased, so that it is possible to prevent the magnetic disk from being damaged.
