At the time of polishing an air bearing surface 12 the edge of the air bearing surface 12 is simultaneously beveled to form edge surfaces 14. The air bearing surface 12 is preferably constituted as a flat planar surface 121 having a tapered surface 122 continuous therewith at the air inflow end. In this case, defining the bevel width in regions IV located at the edge surfaces 14 at opposite sides in a direction perpendicular to the air inflow direction and extending in the vicinity of a ridge portion 131 between the central flat planar surface 121 and the tapered inflow end surface 122 and the bevel width in regions II located ahead of an interface 171 between the slider 1 and a thin-film transducer element 17 as I4 and I2 respectively, the bevel width of an air inflow end edge surface 14 (region V) continuous with the tapered inflow end surface 122 as I5 and the bevel width of opposite side edge surfaces 14 (region III) continuous with the central flat planar surface 121 as I3, (I4-I5)/I5 is restricted to not more than 0.4, (I3-I2)/I3 is restricted to not more than 0.2, the bevel width of all edge surfaces 14 is restricted to 4-20 (my)m, or the bevel width range R thereof is restricted to not more than 5 (my)m. By in this way restricting the bevel width of the edge surfaces 14 over the entire perimeter of the air bearing surface 12 so as to be highly uniform, there are realized marked improvements in flying stability, particularly a reduction in the variation in roll angle in the flying attitude.
