To prevent some photographing data from being magnetically recorded on a frame photographed before a film taken out halfway is loaded by magnetically recording it only on the newly photographed frame when the above- mentioned film is loaded again.

A count means, a film heading means, a photographing information storage means and a magnetic recording control means are constituted of a microcomputer MCU. A magnetic recording/reproducing means is constituted of a magnetic write circuit U4, an amplification circuit U5 and a magnetic head 87. A frame storage means is constituted of an EEPROM. By setting an unexposed frame at a photographing position, a heading action is executed and a frame value obtained when the heading action is finished is stored. When the frame is exposed, the photographing information of the exposed frame is stored. When a film is rewound, the photographing information of the frame exposed this time is read out and magnetically recorded on the respective frames. However, it is not magnetically recorded on the frame being smaller than the heading frame value.
