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.
