Appeal No. 1998-0866 Application No. 08/698,707 page 5). Clearly each of Swanson and Brock teach the recording device is to record on the magnetic strip only and 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 roller periphery "constitutes a series of continuously- repeating complete identical messages" (claim 4) and "are sufficiently short to ensure that at least one of the identical messages will be recorded on the magnetic track for each exposed frame of the filmstrip" (claim 5). Swanson discloses that the roller wheel depositing the information onto the magnetized strip "can make one complete revolution within the space of a single frame" (col. 5, lines 15-16) and "the pattern can be repeated around the roller wheel, providing redundant patterns, if desired for error checking or other safeguard against slippage" (col. 5, lines 19-22).
