That sounds exactly like Kodak disc film, its not for projection, you print the pictures from the negatives. Disc film was never much of a success as firstly it had very small negative (even smaller than the earlier 110 film) and to print it you were supposed to use a newer 6 element enlarging lens designed for the smaller format.
Unfortunately not a lot of labs (apart from Kodak ones) bothered buying these new lenses, they just continued using the old 3 element lenses for larger formats so the prints were usually quite disappointing. Kodak eventually stopped making disc film in 1999 although they had stopped production of the actual cameras years before. Incidently though, the emulsions on disc film were usually a couple of generations ahead of other film types as it was Kodak's policy to test new emulsions on disc film first (to see if it could improve the mediocre quality).
