ABSTRACT:
A system for recording information related to the camera exposure parameters of film image frames in a detachable, disc-shaped, memory module attached to the end of a film cartridge loaded in the camera in non-volatile memory for subsequent read-out. A set of concentric, circular, conductive bands are spaced apart and electrically isolated from one another on the exposed surface of the disc-shaped module housing. An integrated circuit chip, including a non-volatile memory, within the module, has a plurality of input and output terminals connected to the plurality of concentric conductive bands. A camera receives the film cartridge and attached memory module in a cartridge receiving chamber and has a plurality of contact terminals positioned to make electrical contact with the respective plurality of concentric conductive bands. The camera electronic operating system provides the battery power and electrical signals to be stored in the non-volatile memory through contact of the plurality of contact terminals with the respective concentric conductive bands. The stored data may be read out through the concentric, circular conductive bands and employed in processing and/or making prints from the film in the cartridge.
