Abstract
A disc memory cartridge double-acting handle design increases, over an earlier design, the amount of material resisting stresses at critical points to increase overall stiffness and strength. The increased stiffness and strength allows plastic to be used as the structural material for the mechanism, rather than the metal of the earlier design. The manipulation required is unchanged from the earlier design.
