    摘要： A thin film magnetic recording head and process for fabricating it is disclosed. The magnetic recording head has a core with a gap the same length as the width of an original document to be produced and is positioned in contact with a moving magnetic recording medium and perpendicular to the direction of movement thereof. A high magnetic permeable body is disposed in the gap of the head core and is in contact with the magnetic recording medium. A heat generation body of the same length as the high magnetic permeable body is positioned in contact therewith. Means for selectively heating segments of the heat generation body corresponding to the width of a picture element is provided. The portions of segments the high magnetic permeable body that are heated via the heat generation body segments, above its curie point are rendered non-magnetic forcing the magnetic flux generated in the core by an exciting coil external of this portion and into the magnetic recording medium, thus forming latent magnetic images in the recording medium.

    摘要： A thermomagnetic printer includes a recording unit for storing a latent image in which there are provided a magnetic recording layer providing thermomagnetic effect when placed in magnetic field with temperature graduation on one side of a photoconductive layer and a transparent electrically conductive layer on the other side.When storing a latent image in the magnetic recording layer, light which emits corresponding to the image to be reproduced on a paper is irradiated onto the photoconductive layer through the transparent electrically conductive layer while applying magnetic field to the magnetic recording layer and supplying electricity between the magnetic recording layer and the electrically conductive layer, whereby irradiated part of the photoconductive layer and the corresponding part of the magnetic recording layer are heated by Joule heat effect and the latter is magnetized by the thermomagnetic effect. By repeating the above operation in accordance with the image information, the latent image is formed in the magnetic recording layer.

    摘要： In a magnetically recording and erasing the magnetic latent image on the magnetic recording medium, the magnetic recording medium includes a base layer, a first magnetic layer in which a repetitive magnetic pattern is in advance formed, and a second magnetic layer on which the magnetic latent image to be formed is thermo-magnetically formed. A method of erasing the magnetic latent image on the second magnetic layer includes the steps of simultaneously applying an external magnetic field and heat to be thermally magnetized layer of a magnetic recording medium.
