ABSTRACT:
When a supply tape guide of a VHS or Betamax videocassette is plastic rather than the usual stainless steel, equal or better performance is attained when the plastic is a blend of acetal copolymer and a small proportion of lubricant and anti-static agent. The same plastic may be used for either or both of the supply sleeve and the supply pin, and both can be molded of that plastic as a single piece.
