FLOATING HEAD SLIDER, FLOATING HEAD APPARATUS AND DISK DRIVING APPARATUS

摘要

A floating head slider for a disk driving apparatus, which floats above a disk-like recording medium when this medium is rotated. The head slider includes an air lubrication surface formed on the surface opposed to the disk-like recording medium; a tapered portion on the air inflow side of the air lubrication surface; a recess along the center line extending from the air inflow side of the air lubrication surface to the air outflow side, the recess having the air inflow side thereof closed and the air outflow side thereof open and having a predetermined depth to generate a negative pressure; and a groove extending from the recess to the end of the air inflow side of the air lubrication surface along the center line, and being wider than the recess which divides the air lubrication surface but having the same depth. This head slider can float a predetermined distance above the surface of the disk recording medium in a stable state due to the positive pressure occurring on the air lubrication surface and the surface of the disk-like recording medium driven for rotation and the negative pressure generated by the recess.
