A one-track tape recorded on both sides for 90 minutes of audio. The tape is twisted to form a Möbius loop so that both sides of the tape are eventually played. Although similar in size, it's not compatable with players for the Fidelipac C cartridge.
Rediffusion later came out with a system that used a smaller, 4-track cartridge.
