Abstract
A head slider is composed of a substrate having a transducer on its outflow end, a rail plane formed on a surface near both sides of the substrate facing a magnetic disk. The head slider further includes a plurality of projection elements formed on the rail plane. When the slider is floating over the magnetic disk, the distance between the projection elements and the magnetic disk is greater than the distance between the outflow end of the slider and the magnetic disk.
