ABSTRACT:
A virtually transparent magnetic layer is included as an additional layer in a photographic film strip. Information exchange between various users of the film such as, for example, the film manufacturer, the camera user, the dealer and photofinisher, is facilitated by plural longitudinal magnetic tracks on the film that begin and end within individual frames. Each track is dedicated to the writing and reading of a predetermined set of parameters relating to the corresponding frame, for easy access by a particular one of the various users. Each user has the capability to read and/or write informaton in self-identifying data fields in the corresponding tracks.
