Abstract:
A magnetic head slider having an air flow inlet side, an air flow outlet side, and a plurality of surfaces between the inlet side and the outlet side for constituting fluid force generating parts for the magnetic head slider due to dynamic pressure effects of air flow accompanying rotation of a magnetic recording medium, each of the plurality of surfaces having a different height level for defining a different distance to a surface of the magnetic recording medium, the magnetic head slider comprising:a contact pad supporting a magnetic head for recording and reproducing data to and from a magnetic recording medium to enable the magnetic head to contact the surface of the magnetic recording medium, the contact pad being provided near the air flow outlet side at a top level of the plurality of height levels, and the contact pad being surrounded by a surface being positioned at a lower position of a middle level of the plurality of height levels; a positive pressure pad area provided near the air flow inlet side, the positive pressure pad area being positioned at the top level; and a squeeze pad area provided along an air flow direction on both sides of the head slider at the middle level, the squeeze pad having a sufficient surface area for having a squeezing effect behind a moving direction of the head slider, and a distal end of the squeeze pad area reaches near a trailing edge in order to obtain a squeeze film effect for avoiding shocks at a loading time.
