Abstract
A head-slider which is configured to fly above a magnetic-recording disk. The head-slider includes a disk-facing side, which faces the magnetic-recording disk. The disk-facing side includes a plurality of surfaces including at least: a step bearing surface; a rail surface, which protrudes toward the magnetic-recording disk and is configured to exert a positive pressure; a deep-recessed surface, which is formed deeper than the step bearing surface and is configured to exert a negative pressure; an extended lateral surface, which is formed at substantially a same depth as the step bearing surface and disposed outside the deep-recessed surface in a width direction of the head-slider; and, an extended rear surface, which is formed at substantially the same depth as the step bearing surface and disposed at a trailing edge of the head-slider, and contiguous with the extended lateral surface.
