Head suspension mounting system with positive orthogonal alignment features

This invention relates generally to the field of hard disc drive data storage devices, and more particularly, but not by way of limitation, to an improved mounting system for attaching the head suspensions that support the read/write heads to the head mounting arms of the disc drive actuator. A mounting system attaches head suspensions to actuator head mounting arms of a disc drive actuator. The mounting system includes head suspension mounting plates and features on both the head suspension mounting plates and on the actuator head mounting arms that facilitate snap-fitting or press-fitting of the mating components, as well as features that ensure both accurate alignment and maintenance of the position of the mounted head suspensions in and about the major orthogonal axes.
