Even in 9-5 mm., the magnetic stripe does not detract from the projected picture width even though it encroaches on the exposed picture. A 30-mil balancing stripe is commonly added on the left of 16-mm. film to promote good spooling. cameras have the claw on the left and this is why you cannot buy single-perforated stock in magazines. If you want to make magnetic sound films with a magazineloading camera, you can, of course, have reversal duplicates made on to single-perforated stock.
