Hovering-type head slider and magnetic disc device

Disclosed is a hovering-type head slider in which the variation in static hovering distance is reduced as much as possible, thereby making it possible to obtain a hovering distance which is constant with respect to variation in the skew angle and in the linear velocity. The hovering-type head slider includes two rails 16 and 17 which are formed on either side portions of the surface thereof opposed to a recording medium and which serve as air bearing surfaces, a tapered portion provided on the air flow inlet side of each rail, and a magnetic head 15a provided on an end surface on the air flow out let side, wherein the rails 16 and 17 branched into branch rail portions which extend obliquely toward the air flow outlet end from a position near the center with respect to the direction of the air flow.
