A magnetic head slider, for sliding on a magnetic disk, which comprises a leading edge, a trailing edge, an air bearing surface having a front step bearing of submicron depth made from the leading edge, and a rail surface made from the front step bearing. A negative pressure recess, which is more profound than the front step bearing, is made from the rail surface, and a side step bearing with a depth identical to that of the front step bearing is made from the rail surface, wherein the ratio of depth R of the recess and depth &#x3b4;s of the front step bearing is R/&#x3b4;s&#x2267;5.
