PURPOSE:To simplify the constitution while holding a picture quality by heating a magnetic recording medium under a prescribed magnetic field by minute heating bodies arranged with a high density to form a magnetic latent image. CONSTITUTION:Minute heating resistors 2 are provided which are arranged linearly with a high density orthogonally to the advance direction of a thermomagnetic recording medium 1 whose magnetic characteristics are changed by temperature, and the medium 1 degaussed by a degaussing device 4 is fed out to a heating head array 3. The medium 1 in the peripheral part of resistors 2 is magnetized by a permanent magnet 10, and resistors 2 are heated by a heating command of a control part 12 corresponding to recording information, and the recording medium 1 is heated partially to form a magnetized pattern 20. The pattern 20 has a size corresponding to the size of heads of heating resistors 2 and is developed by a developing device 7 and is printed. Thus, the picture quality is held with a simple constitution. |
