Abstract
A tape drive capstan has a porous ceramic matrix in the form of a cylindrical shell using spherical ceramic particles bonded together to form a network of interstitial pores which are substantially uniform in size and interconnected. A urethane elastomer is impregnated into the pores to form a tape driving surface on the outside surface of the cylinder. The outer surface of the capstan is finish-ground to an outside diameter suitable for use in a tape drive apparatus. The particles occupy approximately 70% of the internal volume of the shell and the elastomer occupies the remaining 30%. The shell is attached by an epoxy to an outside surface of a drive shaft suitable for driving the capstan.
