Abstract
A camera is capable of recording plural kinds of data at corresponding positions of each film frame. In a first operating mode a first kind of data is recorded at a first position in the film frame disposed at an exposure location, and film feeding is started. Film feeding is suspended temporarily, and a second kind of data is recorded at a second position of the frame. Then film feeding continues to bring a subsequent frame to the exposure location. If no second kind of data is to be recorded or if no data of any kind is to be recorded, the film feeding is not temporarily suspended. Data recording may occur in the course of film winding or film rewinding. Some or all of the data may be stored before recording, and the order of the recording of kinds of data may be changed, e.g., at the last frame of the film. In some embodiments the film is rewound by a fraction of a frame before recording of a second kind of data.
