ABSTRACT:
A magnetically recordable photographic film has perforations each being in at least one side edge region of the film lying between adjacent image areas (frames). A magnetic recording track region extends throughout the overall length of the side edge region adjacent to each frame in at least one side edge of the film. Camera information is recorded on the side edge track region. Information is read and rewrote on the film in camera. Film information is recorded on the leading end of film, and recording extension may be provided additionally. The film information is read and recorded on the film for each of the frames. Signals for clock and data are based on three-bit encoded data, and a pulse period can be varied depending on film transport speed. Such signals may be selected to have a frequency corresponding to the film transport speed.
