Data is recorded on the frame portions of the magnetic recording portions 59 and 61 of the film corresponding to the data. That is, in the second embodiment,
Since the data is recorded when the film is rewound, the data is recorded not in the film winding direction but in the film rewinding direction. And record a series of data,
When the film rewinding is completed, this sequence is completed.

According to the second embodiment, the same effect as that of the first embodiment can be obtained, and the recording of the data on the film is performed at the time of rewinding. Even when feeding is necessary, it does not take much time as in the case of recording data for each frame shooting, so that high-speed frame feeding can be supported. Further, when data is recorded at the time of frame feeding, there is a possibility that reliable recording cannot be performed unless the frame feeding is performed stably. However, according to the second embodiment, such recording is performed on the film. Since the film can be rewound during stable running of the film, stable and reliable data recording can be performed.
