ABSTRACT:
A disk drive suspension load beam having reduced mass for lessened shock in use and progressively modified stiffness and torsion values from its rearward portion to its forward portion is provided by trenching the rearward and/or intermediate portions to form on the flexure bearing, or opposite, face of the load beam a longitudinal series of transverse grooves in the rearward portion and in the intermediate portion inside the edge margin thereof, suitably cross-ribbed for stiffness, the rearward portion trenches being on the opposite face unless the intermediate portion is also trenched.
