Abstract
A camera uses a film with a magnetic memory portion and includes a film transporting circuit for transporting the film, a magnetic operation circuit for writing or reading information to or from the magnetic memory portion of the film during the film transporting operation by means of the film transporting circuit and control circuit for controlling the film transporting circuit in such a manner that a film transporting speed at the time information is written by the magnetic operation circuit is slower than a film transporting speed at the time the information is read by the magnetic circuit.
