Abstract:
A flying type head slider having a rear surface which faces a recording surface of a magnetic disk comprising:a center rail formed on the rear surface of said slider, said center rail having a regularly rectangular shape with straight parallel side walls which extend along the full length of said center rail;a magnetic head disposed on said slider so as to be aligned with said center rail and proximate an edge of said slider;a pair of side rails formed on the rear surface of said slider, said pair of side rails respectively having regular rectangular shapes with straight parallel inner and outer side walls which extend along the full length of each side rails, said side rails being respectively located on either side of said center rail, the inner side walls of said side rails respectively facing a side wall of the center rail, the outer side walls of said side rails having a surface which is angled relative to a side wall of the center rail such that the magnetic head floats above the recording surface of the magnetic disc on a supporting force generated by air flowing between the rails and the recording surface of the rotating magnetic disk, wherein said side rails have chamfer-like tapered portions and are symmetrically disposed on the rear surface in a non-parallel angled relationship with respect to the center rail.
