Abstract
A reel flange for a magnetic tape cassette reel has apertures for viewing the tape on the reel. The apertures provide a system for visually estimating the quantity of tape contained on the reel. The flange provides the combined advantages of greater choice of materials for making the flange and improved accuracy in estimating the quantity of tape contained on the reel.
