record the desired information. Brock teaches a magnetic head
recording device 60 (Fig. 1) which is mounted internal to the
camera along the magnetic track on the filmstrip. Brock
teaches the elements of appellants claim 1 except for the
specific type of recording device. Swanson discloses
recording onto the magnetic strip of film with different types
of recording devices (linear array 18 of Fig. 1 or magnetic
roller 106 of Fig. 3). Other types of recording devices are
discussed, for example "[t]o increase the amount of data that
can be recorded in a fixed length of magnetic media, such as a
frame of a photographic filmstrip, multiple roller wheels may
be provided" (col. 5, lines 23-26). We find that it would be
obvious to modify Brock by providing the roller type of
recording device of Swanson in place of the magnetic head
shown by Brock. The choice of the type of recording device is
an obvious choice as taught by Swanson, and is dependent on
factors such as the amount and type of information to be
recorded. It would have been obvious at the time the
invention was made to a person having ordinary skill in the
art to modify Brock's camera and recording mechanism by
