ABSTRACT:
A disc drive including a dual disc clamp for clamping a number of hard discs within a disc drive is disclosed. The clamp is comprised of a top circular clamp member in contact with a bottom circular clamp member, with the clamp members having the same physical shape and area. The bottom clamp member has number of holes formed therein which reduce the disc distortion. The top clamp member has a concave upper surface, while the bottom clamp member has a convex upper surface. The clamp holds the discs in place through pressure provided by a plurality of screws which are passed through holes in the clamp members. The disc drive also includes a spindle motor to which the dual disc clamp is connected. The spindle motor provides a greater torque constant, thereby allowing lower start and run current.
