ABSTRACT:
Magnetic image recording methods and apparatus employ a magnetic recording medium susceptible to an image-wise change of magnetization in response to thermal image patterns provided by image-wise exposures of a thermal image pattern generating device. The thermal device is subjected to repeated image-wise exposures, with each exposure including an exposure to an image part to which the thermal device is also exposed during another one of the exposures. The thermal device is moved relative to the recording medium between exposures, and the image is magnetically recorded onto the recording medium with the aid of thermal image patterns generated by the exposures.
In accordance with another aspect, the mentioned thermal device is exposed at different spatial locations to each elemental area of the image. The exposed spatial locations as to each elemental image are brought into coincidence relative to the recording medium, and the image is magnetically recorded onto the recording medium with the aid of thermal image patterns generated by the mentioned exposures.
