Abstract
A floating-type head slider having a rail plane that functions as an air bearing in accordance with a kinetic pressure of an air flow caused by rotation of a recording medium, that supports a recording/reproducing device for recording and reproducing information, and that keeps a predetermined gap between the device and a surface of the recording medium, wherein an edge of the rail plane includes only segments of ellipses and circles, and tangent lines of the segments, preferably the edge of the rail plane is continuous to provide a floating head slider having high reliability even in a dusty environment and a recording/reproducing apparatus in which such a floating head slider is employed.
