Abstract
A head slider having a disk opposing surface, an air inlet end, and an air outlet end. The head slider includes a front rail formed on the disk opposing surface in the vicinity of the air inlet end, the front rail having an air bearing surface and a step surface lower in level than the air bearing surface; a transducer formed in the vicinity of the air outlet end; and a first groove for expanding air once compressed by the front rail to generate a negative pressure. The head slider further includes a second groove formed on the step surface near the air inlet end except opposite side portions of the step surface. The step surface reaches the air inlet end at the opposite side portions.
