Air bearing slider with corner steps

An air bearing slider for a disc drive comprising:

• a slider body having a disc opposing face comprising:
• a leading edge;
• a trailing edge opposite the leading edge and defining a length of the slider body;
• side edges running from the leading edge to the trailing edge, the side edges intersecting the leading edge at leading corners, the side edges intersecting the trailing edge at trailing corners;
• an air bearing surface defined on the disc opposing face at least in part by a first cavity, the air bearing surface being substantially flat, the first cavity having a substantially flat first cavity surface substantially parallel to the air bearing surface at a first cavity depth from the air bearing surface, the air bearing surface being disposed inward from at least one of the leading corners and trailing corners;
• a second cavity having a substantially flat second cavity surface substantially parallel to the air bearing surface at a second cavity depth from the air bearing surface different from the first cavity depth;
• and
• a corner step extending for only a portion of the length of the slider body, the corner step having a substantially flat corner step surface substantially parallel to the air bearing surface at a corner step depth from the air bearing surface, the corner step including said at least one of the leading corners and trailing corners, wherein the corner step depth is greater than the first cavity depth and different from the second cavity depth.
