Claim:
A head slider comprising: an air inlet end; an air outlet end; a disk inner edge side; a disk outer edge side; and a front surface for opposing a disk-shaped recording medium, said front surface including: a positive pressure generating section; a flotation improving section arranged to oppose the disk-shaped recording medium, said flotation improving section confronting said positive pressure generating section; a negative pressure generating recess between said positive pressure generating section and said flotation improving section; a head for performing at least one of a recording operation and a playback operation on the disk-shaped recording medium, said head being fixed at a downstream side of said flotation improving section; and a sloped face at both lateral sides of said head, and extending from a downstream side of said negative pressure generating recess to at least one of said air outlet end, said disk inner edge side, and said disk outer edge side, and being arranged such that a distance from the disk-shaped recording medium to said sloped face is gradually larger from an air inlet side of said sloped face toward an air outlet side of said sloped face when said head slider is steadily afloat over the disk-shaped recording medium.
