ABSTRACT:
Drive belts for tape cartridges featuring a base belt of low coefficient of elasticity with an elastomeric coating having a high coefficient of friction. Three examples of such belts are: (1) polyimide or polyester film base belts with a thin elastomeric film coating; (2) nickel, copper or steel base belts with a thin elastomeric film coating and (3) spirally wound filaments of high modulus of elasticity within an elastomeric matrix having a low modulus of elasticity, the filaments forming the base belt and the elastomeric matrix forming the coating on the base belt, holding the spiral loops in place.
