Abstract
A magnetic disk drive includes a magnetic recording medium and a magnetic head slider adapted to fly over a surface of a magnetic recording medium and read or write information. The magnetic head slider includes a slider air bearing surface and a magnetic transducer. The slider air bearing surface includes a front pad having front rail surfaces and front step bearing surfaces, a rear pad having a rear rail surface and a rear step bearing surface, and a negative-pressure groove interposed between the front pad and the rear pad. A vibration suppressing groove is formed in the rear rail surface so as to be deeper than the rear rail surface and to be closed at its periphery. The vibration suppressing groove quickly damps out translational and pitching vibrations in the flying height direction of the magnetic head slider while stabilizing its flying.
