Abstract
In a magnetic recording apparatus for a camera using a film having a magnetic recording portion, a magnetic recording device records photographic data on the magnetic recording portion while the film is wound after a photographic operation corresponding to one frame is completed. An electrically erasable nonvolatile storage device stores the photographic data after the photographic operation corresponding to one frame is completed. A magnetic reproducing device reproduces the photographic data recorded on the magnetic recording portion while the film is rewound. A determining device determines whether the photographic data reproduced by the magnetic reproducing device coincides with the photographic data stored in the storage device. When the determining device determines that the two photographic data do not coincide with each other, a re-recording device causes the magnetic recording device to re-record the photographic data stored in the storage device on the magnetic recording portion. An erasing device erases the magnetically recorded data when the determining device determines that the two photographic data do not coincide with each other.
