Abstract
A magnetic head slider having an air inlet end surface and an air outlet end surface, including a pair of rails formed on a disk opposing surface opposed to a magnetic disk, each of the rails having a flat air bearing surface for generating a flying force during rotation of the magnetic disk and a tapering surface formed continuously to the air bearing surface so as to meet the air inlet end surface; and an electromagnetic transducer formed on the air outlet end surface at a position where one of the rails is formed. The magnetic head slider further includes a pair of projections each formed continuously on the tapering surface and the air bearing surface of each rail, each of the projections extending to a peripheral edge of the air bearing surface.
