ABSTRACT:
A device for recording predetermined magnetization patterns on a magnetic recording medium such as for use in a copying machine. The magnetic medium is first magnetized with a uniform magnetization pattern then passed to a thermal printing head upon which a number of heat generating elements are arranged one-dimensionally on a supporting substrate. The heat generating elements are selectively activated to heat the recording magnetic medium to a temperature greater than the Curie temperature thereof so as to change the direction of the magnetization of the magnetic medium in cooperation with a biasing magnetic field.
