Abstract:
1. A head slider having an air inlet end, an air outlet end, and a disk opposing surface opposed to a disk, comprising: a front rail formed on said disk opposing surface at a longitudinal position adjacent to said air inlet end, said front rail having a flat air bearing surface for generating a flying force during rotation of said disk; a pair of rear rails formed on said disk opposing surface at a longitudinal position adjacent to said air outlet end, each of said rear rails having a flat air bearing surface for generating a flying force during rotation of said disk; a groove formed downstream of said front rail for generating a negative pressure by expanding air once compressed at said front rail; a transducer formed near said air outlet end at a transverse position where one of said rear rails is formed; and a plurality of pads formed on said front rail and on at least one of said rear rails; wherein at least said pads that are formed on said front rail have a side surface substantially normal to said air bearing surface of corresponding said front and rear rails, a first height, a second height and an inclined upper end surface extending from said first height to said second height with a given inclination angle such that the upstream end of said inclined upper end surface is higher in level than the downstream end thereof.
