Abstract
Protruding portions are formed on outflow ends of slider rails on a floating magnetic head slider. This floating magnetic head slider is of rails type. Each of the protruding portion extends farther to the outside as it approaches the outflow end. Or the external sides of the rails on the magnetic head slider are so arranged that angles formed thereat diverge from the side of the inflow end to the side of the outflow end, and a pressure adjusting aperture is formed on the outflow side of each of the rails. Because of the above arrangement, it is possible to provide a magnetic head unit in which particles, such as dust, adhering to the disk surface are effectively removed, and in which floating stability is not impaired. Removing the particles on the disk surface is not limited by seeking directions even while the magnetic disk unit is in operation.
