Abstract
A head slider has, on its front face opposing a disk, a positive pressure generating section and a negative pressure generating recess, and a sloped face slopping toward the air outlet side. By virtue of the sloped face, the negative pressure hindering with high-speed unloading operation of the head slider can be decreased quickly. Thus, at the time of unloading, an additional load is not necessary for the suspension, and the stroke of the suspension for raising the head slider can be shortened. Therefore, a disk drive which is thinner, smaller, and capable of high recording density can be realized.
