Abstract
A tape cassette is described having top and bottom cassette halves, tape reels and low friction washers between the tape reels and the cassette halves. Each tape reel is made of a plastic hub connected to two plastic flanges, each flange having intentionally curved circumferential edges. Each flange also has a raised, annular centering ring abutting and rotating only on the washers for rotatably supporting the tape reels relative to the tape cassette. These centering rings minimize friction, prevent skewing of the tape reels relative to each other and, along with the curved edges of the flanges, permit the tape to be wound without damage.
