A cartridge to be loaded with a length of film or other strip material is adapted to be positioned in a sound motion picture camera, projector or other sound recording or reproducing apparatus. The cartridge has an open area across which the strip material extends so that the strip material in this area can cooperate with the sound mechanism of the apparatus. A guide finger is positioned with respect to the open area in the cartridge to contain the strip material within the cartridge body, thereby facilitating insertion of the cartridge into the apparatus.
