ABSTRACT:
A thermoremanent imaging apparatus for magnetically recording graphic information is disclosed. An elongated light source with a substantial infra-red and visible radiation spectrum is used to produce a high energy flash exposure of a magnetic surface. The light source is co-axially located within a transparent cylindrical transport means which carries the magnetic surface around its periphery. A uniform intensity of energy from the flash exposure over the entire magnetic surface is provided by reflective energy deflecting means placed in opposition along the axis of the transport means.
