摘要： 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.
摘要翻译：在使用具有磁记录部分的胶片的相机的磁记录装置中，磁记录装置在与一帧相对应的拍摄操作完成之后在胶卷被卷绕时将照相数据记录在磁记录部分上。电可擦除非易失性存储装置在对应于一帧的摄影操作完成之后存储照相数据。当磁片重新卷绕时，磁再现装置再现记录在磁记录部分上的照相数据。确定装置确定由磁再现装置再现的拍摄数据是否与存储在存储装置中的摄影数据一致。当确定装置确定两个照相数据彼此不一致时，重新记录装置使得磁记录装置将存储在存储装置中的摄影数据重新记录在磁记录部分上。当确定装置确定两个照相数据彼此不一致时，擦除装置擦除磁记录数据。
