Film scanner and method of reading optical information using same

An APS (Advanced Photo System) film of new type has a plurality of image recording areas along the center thereof, a first longitudinal side edge of the film is formed to have perforations corresponding to the image recording areas, and a second longitudinal side edge of the film is formed to have optical information recording areas corresponding to the image recording areas. While the APS film is being conveyed in its longitudinal direction the perforations are sensed and optical information in the optical information recording areas is read with the sensed perforations serving as a reference.
