US Patent 7095592 Head slider and disk drive apparatus

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.
