Abstract
This application discloses a hard disk drive comprising a landing ramp mounted to a disk base including a slider limiter for at least one slider in the hard disk drive to limit movement of the sliders during a non-operational shock event while parked on the loading ramp. Each of the slider limiters includes a clearance zone configured so that when the slider contacts the slider limiter during the non-operational event, the read-write head remains out of contact with the slider limiter. The clearance zone may include a recess and/or a cutout. The clearance zone may include a recess and/or a cutout. The recess may take any shape, for example the recess may be a polygon and/or curved in cross section. The polygon may have at least two sides. The clearance zone may further include a radial bulge to further protect the read-write head during non-operational shock events.
