Abstract
Abstract A magnetically recordable photographic film has perfortions each being in at least one side edge region of the film lying between adjacent image areas (frames). Magnetic recording track region extends throughout overall length of the side edge region adjacent to each frame 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 frames. Signals for clock and data are based on three-bit encoded data, and pulse period t can be varied depending on film transport speed. Such signals may be selected to have a frequency corresponding to the film transport speed.
