Disclosed is a head slider having excellent shock resistance, a head
supporter, as well as a disk drive using the head slider. The head slider
is characterized in a form of its opposite-to-disk surface, such that a
fixed point is set at a position located outwardly of a rear end portion
of the head slider and at a predetermined distance from a load
application point, which load urges the slider toward a disk. When a
shock force is externally applied to the head slider, the head slider is
rotated about this fixed point such that at least one of pitch angle and
roll angle is maintained positive. Because of this structure, a disk
drive excellent in shock resistance can be provided.
