Abstract
A method for making endless metallic ribbon drive belts for tape cartridges. Metal is electroformed on a steel ring sandwiched between two non-conductive discs. After removal from the steel ring, the plated ring is thinly coated with an elastomeric coating resulting in a compound belt having a low coefficient of elasticity in the base belt and a high coefficient of friction in the coating.
