A camera is capable of writing data into, and reading data from, a magnetic recording layer formed on photo film. An exposure chamber has a pair of inner rails along horizontal sides of an exposure aperture. Outside the inner rails, a pair of outer rails are formed. Rear faces of the inner rails receive the photo film. Rear faces of the outer rails contact the film support plate. In the film support plate, the magnetic head is mounted. The film support plate is fixed on the exposure frame, and defines a film tunnel between it and the exposure frame. The film support plate has four pins, which regulate each position of longitudinal edges of the film while moved through the film tunnel. The film is guided by the four pins on the film support plate, and is kept to have a position relative to the magnetic head, so as there to be no track deviation or azimuth deviation.
