Abstract
A rail is formed on a medium-opposed surface of a slider body in a flying head slider. An air bearing surface is defined on the upper surface of the rail, which faces the medium. Projections are formed on the medium-opposed surface. The projections serve to space the air bearing surface from a medium such as a recording disk when the slider body contacts the recording disk. A trailing end of the rail is narrowed laterally along the trailing end of the medium-opposed surface. Even when the slider body contacts the recording disk at the trailing end, in addition to the projections, the contact area between the slider body and the recording disk is reduced because of the narrowed trailing end. Since the rail is narrowed without changing its original thickness or height from the bottom base of the medium-opposed surface, no additional processing is required to form the air bearing surface.
