ABSTRACT:
A camera which uses a film cartridge having a magnetic recording part for each frame portion thereof and writes magnetic information in the magnetic recording part of each frame, in rewinding the film after completion of photographing on all frames, is arranged to effectively prevent information from being recorded again at the time of rewinding the film for any frame having magnetic information already recorded in a case where the film cartridge loaded into the camera contains a film in which part of frames have been already exposed. In the camera, when a film cartridge having some of film frames already exposed is loaded, the camera stores the position of a leading unexposed frame and to permit recording of magnetic information up to the leading unexposed frame in performing the recording action at the time of film rewinding.
