Printing and duplicating are carried out utilizing the thermoremanent magnetization of a magnetic thin film. Information is stored by heating the film above its Curie temperature and allowing it to cool in a small magnetic field. A copy of the latent image is made by coating the magnetized areas of the film with a magnetic ink and transferring the ink to paper. The film is locally heated by selective heating with a light source, preferably a laser.
