Standardization of cartridge systems is very desirable for the industry assuming certain criteria are met. Such a standard system should be: easy to use; reliable; of minimum cost; versatile, so as not to restrict the use of other projector features such as multiple play, rewind, and high or low speed projection; and adaptable, both to different markets and to various projector design. The Bell & Howell open loop or reel type rim drive cartridge system is described as a system to meet all the criteria given.
