ABSTRACT:
A camera uses a film cartridge containing photographic film having a magnetic medium for the recording of data by a magnetic head of the camera. To clean the head a cartridge containing a cleaning film is loaded in the camera. The camera detects the loading of this cartridge, inhibits the operation of an exposure mechanism, and winds and rewinds the cleaning film. The number of cleaning operations may be stored in a memory of the camera, and the cleaning film may have a magnetic medium on which the number of cleaning operations by the cleaning film is recorded by the magnetic head and from which the number of recorded cleaning operations is read by the magnetic head.
