Abstract:
A magnetic disk unit comprising:a magnetic disk attached to a spindle so as to be rotatable; a slider which has a first pad and second pads, and said first pad, which stays in contact with said magnetic disk, has a magnetic head for reading/writing data onto/from said magnetic disk and is located substantially in a center of said slider in a width direction; a suspension which provides said slider with a predetermined load; a gimbal coupled to said suspension; an actuator arm which positions said slider attached to said suspension on said magnetic disk; and a positive pressure rail for generating negative pressure on the leading edge side of the first pad; wherein, the positive pressure rail having an open side, and partially surrounding a negative pressure recess formed to generate negative pressure; wherein a magnitude of a flying force generated by said positive pressure rail is substantially equal to a magnitude of the negative pressure generated by said negative pressure recess; wherein said slider being provided a pitch moment in such a direction as to make said first pad approach said magnetic disk; wherein said pitch moment being generated by said predetermined load upon a load point of said suspension with respect to said slider.
