Abstract
A disc drive assembly constructed in a manner to avoid relative movement of the actuator arms relative to one another even under shock or other substantial forces comprises a flange, actuator arm supports, voice coil support and appropriate spacers, with a nut on the bottom of the pivot stack assembly supporting the above named components setting the relative position of these pieces relative to the pivot cartridge. Each above identified element of the stack is then laser welded to an adjacent piece in order to prevent rotation of any actuator arm. The pieces are laser welded at a curved edge of the part where the parts are rounded so that the adjacent edges lie very close to each other.
