to avoid contamination of the picture portion. We find that
at the time the invention was made a person having ordinary
skill in the art combining the teachings of Brock and Swanson
would provide that the roller be limited to printing on the
magnetic strip without contaminating the picture portion of
the film.
Appellants' claims 4 and 5 further limit claim 1 by
providing that the information magnetically stored on said

sufficiently short to ensure that at least one of the
