Patent ID: 7542238

Claim:
A magnetic head slider comprising: an air inlet end; an air outlet end; and an aerodynamic structure; wherein the aerodynamic structure includes: a plurality of inlet rails respectively having inlet rail surfaces; an outlet rail having an outlet rail surface flush with the inlet rail surfaces and supporting a magnetic head; a bearing surface extending at a predetermined first depth δ 1 from a reference plane including the inlet and the outlet rail surfaces; a negative-pressure surface extending in a plane at a predetermined second depth δ 2 greater than the first depth δ 1 from the reference plane; and longitudinal lands of a predetermined height h formed on and extending between opposite sides of the inlet rails; and wherein the bearing surface and the inlet rail surfaces extend between the air inlet end and the lands; wherein the outlet rail surface and the inlet rail surfaces include rising diagonal surfaces formed at the air inlet end; wherein the inlet rails extend from a position away from the air inlet end to a middle area of the slider at a position before the air outlet end.
