Abstract
A system and method are disclosed for improving the vibration/mechanical shock-resistance of a hard disk actuator arm. A guide block is located behind the actuator arm's angular range of motion, preventing over-flexure/vibration during operation, and/or the drive's actuator screw head diameter is increased to minimize arm vibration.
