A disc assembly, a method for producing the disc assembly, and a corresponding disc drive for recording and reading digital information is disclosed. The disc assembly is assembled without using mechanical fasteners and adhesives. The disc assembly includes a platter sandwiched between a plastic clamp and a hub that engages with the clamp. The hub has a hole through which a stake is inserted. The stake is heated to form a rivet-like structure that holds the clamp to the hub. Alternatively, the clamp may be pressed into a receptacle, such as a channel, to hold the clamp to the hub. The clamp may have a circular bevel surface to self align the clamp to the platter as it is affixed to the hub. The corresponding disc drive includes a spindle motor, transducer and actuator. Methods for producing the disc assembly are disclosed.
