Flexure mounting system for hard disc drives

In a disc drive data storage device comprising at least one disc member and an array of heads mounted to flexures for encouraging the heads into cooperative engagement with the disc member, the disc drive data storage device comprising an actuator for moving the heads to desired locations on the surfaces of the disc member and the actuator comprising a plurality of head mounting arms, each arm having top, bottom and lateral side surfaces and a proximal end to which flexures are mounted, wherein the invention comprises:

• a system for mounting the flexures to the head mounting arms comprising:
• mounting plates fastened to the flexures, the mounting plates comprising a pair of elongated lateral legs extending substantially parallel with a longitudinal centerline of the mounting plates and in a direction away from the heads, each of said lateral legs being substantially planar, lying in a common plane and having edges parallel to said centerline wherein the edges the edges of said legs closest to said centerline comprising facing edges;
• and
• a pair of slots the lateral surfaces of the head mounting arms, the slots with one slot in each of extending parallel to the centerline and to the proximal end of the arm;
• a respective leg of said pair of legs being mounted in a corresponding of said slots, with substantially the entire length of a facing leg edge lying within a slot;
• whereby the mounting plate lateral legs are brought into engagement with the slots in an interference fit to secure the flexures to the head mounting arms.
