ABSTRACT:
A camera records magnetic data on magnetically recordable film and reduces the effect of magnetic flux emitted from a drive motor of the camera. The drive motor leaks magnetic flux and is located inside a camera windup spool. The magnetic flux is generated from a brush side of the drive motor. A readout head reads out magnetic data from the photographic film and is located between a cartridge compartment and a picture frame of the camera. Accordingly, the readout head is located in a position apart from the brush side of the drive motor thereby suppressing the mixing of magnetic flux generated by the drive motor with magnetic data which has been read out by the magnetic head.
