ABSTRACT:
A magnetic head slider in which a leading pad is projected in a thicknesswise direction of the slider, in comparison with a trailing pad so as to reduce vibration caused by contact between a flat medium surface of a disc and the slider carrying thereon a magnetic head, to reduce variation in flying height caused by wavy unevenness of the medium surface, and to reduce variation in atmospheric pressure around the slider, thereby it is possible to enhance the recording density and the reliability of the magnetic head slider while reducing the costs thereof. Further, a magnetic disc unit using the above-mentioned magnetic head slider.
