ABSTRACT:
With a view to providing a head slider which can suppress the adhesion of dust particles to a flying surface of the head slider when the head slider flies and a disk drive employing the same head slider, a head slider in which at least an air bearing portion and a land portion for forming a vacuum area on the flying surface are provided on the flying surface of the head slider, the land portion being formed in such a manner as to have a difference in level so as to be closer by a step to a disk medium than an end surface of the slider base, wherein the water repellency of an end surface of the land portion and the water repellency of the end surface of the slider base are made higher than the water repellency of the air bearing portion. As this occurs, the water repellency of the end surface of the land portion is increased more than the water repellency of the air bearing portion, whereby the water repellency of the end surface of the slider base can be increased more than the water repellency of the end surface of the land portion.
