ABSTRACT:
In a magnetic image recording device, selected portions of a magnetized magnetic medium are heated to temperatures less than the Curie temperature of the medium to reduce the local magnetization intensity and form a magnetic latent image. If desired, the temperatures of different portions can be varied to produce a shaded image.
