ABSTRACT OF THE DISCLOSURE A magnetic disk assembly is comprised of a magnetic disk and a hub member centrally positioned on that disk and having a non-circular opening for receiving a circular drive shaft which serves to rotatably drive the magnetic disk. The hub member includes at least two reference surfaces which converge toward each other and which form two respective walls of the opening, and one or more resilient members having a surface which forms a third wall of the opening. The three walls are positioned and dimensioned such that when a circular drive shaft is received, the reference surfaces and the surface of the resilient member all tangentially contact the drive shaft to be rotated thereby when the drive shaft rotates.
