1. A system to improve shock resistance of a magnetic storage device comprising:
an actuator screw to secure an arm element and to provide an axis of rotation for said arm element, wherein
said actuator screw includes a crown portion of a diameter and a shaft portion;
said crown portion is in direct contact with a surface of the arm element so as to secure said arm element by uniformly applying axially-imposed compression upon the arm element; and
said diameter is between 28.3% and 50.3% of a width of said arm element, said width taken midpoint of said actuator screw and perpendicular to said arm element.
