Abstract:
A shock-insensitive disk drive suspension comprising a longitudinally extended load beam having a free end, a longitudinal extent and a transverse extent normal to said longitudinal extent, a mounting plate for mounting said load bean to an actuator, said load beam having a base portion affixed to said mounting plate, a spring portion and therebeyond a front portion of a predetermined width to which a flexure is attached, the length of said base portion as a proportion of said load beam being relatively extended and the length of said front portion as a proportion of said load beam being relatively shortened by said mounting plate having an extension at least 50% more in the load beam longitudinal direction than in the transverse direction, said flexure having substantially the width of said front portion and being laminated thereto, said load beam shortening shifting forward the load beam and flexure respective centers of gravity and spacing said centers of gravity a shorter distance apart, whereby the reaction moment Mr of the load beam when the load beam receives a shock force is minimized and thereby the 2nd bending moment excitation of the load beam is reduced.
