A recording disk drive comprises a recording disk. A head slider is supported at the tip end of a resilient suspension so as to face the recording disk. An elastic member is located behind the head slider at a position spaced from the head slider. When an impact is applied to the recording disk drive, the resilient suspension may warp to move the tip end away from the recording disk. The elastic member receives the tip end of the suspension. It is possible to restrain the warp of the suspension, namely, the movement of the head slider. Less resilience can be stored in the suspension. Accordingly, even when the stored resilience causes the tip end of the suspension to collide against the surface of the recording disk, a smaller impact of the head slider against the recording disk may allow less damage to the recording disk or the head slider. Shock resistance to the recording disk drive can be improved.
