Abstract
A spacer ring for reducing the available volume of tape storage on a tape reel. The spacer ring includes a cylindrical annular body which fits around the reel hub. The spacer ring is mounted on the tape reel so as to prevent relative rotation of the spacer ring and the tape reel. The spacer ring mounted on the tape reel can be handled as a single unit by assembly equipment used to assemble tape cassettes. Mounting can be performed with a tab which frictionally fits within a complementarily-shaped opening formed within the tape reel hub. The tape is secured to the spacer ring with an opening formed within the outer surface of the cylindrical body which mates with a complementarily-shaped clip. The spacer ring height at its outer surface is larger than that at its inner surface to eliminate gaps between the spacer ring and reel flanges.
