情報容量を記録することができる。 In the perpendicular magnetization method in which the magnetic recording layer of the magnetic recording body 1 made of a magnetic material having the perpendicular magnetization characteristic is magnetized in the thickness direction (perpendicular direction) in response to a signal to form a magnetic latent image, the magnetic recording When the layer is magnetized in response to a signal, the external magnetic field generated by the magnetization is very sharp. For example, if a square area is magnetized when viewed from the top of the magnetic recording layer, the external magnetic field will be The magnetic field shape is columnar, and the shape of the magnetic field is preserved even at some distance from the top surface of the magnetic recording layer. Therefore, even if a sheet of non-magnetic material (that is, the magnetic field is not changed by the non-magnetic material, which is similar to air with a magnetic permeability of 1) is placed on the surface of the magnetic recording layer, the non-magnetic material will not change. The external magnetic field on the surface of the magnetic sheet does not change much from the external magnetic field on the magnetic recording layer. On the other hand, in the case of the horizontal magnetization method, the external magnetic field is very broad, and even if the external magnetic field in a place close to the magnetic recording layer shows a good pattern, the pattern will be distorted in a place far away. In practicing the present invention, the perpendicular magnetization method is preferred. Furthermore, since the external magnetic field of perpendicular magnetization is sharp, the resolution is high and high-density information capacity can be recorded.

都合である。 Furthermore, by grounding the magnetic recording layer made of a material with relatively low electrical resistance among the magnetic materials with perpendicular magnetization characteristics, that is, one having a volume resistivity of about 10 8 Ωcm or less, an even higher volume can be achieved. If a conductive thin layer is formed on a flexible support and a magnetic recording layer is formed on top of the conductive thin layer, the electrostatic force of charging caused by corona discharge, which will be described later, will cause non-magnetic This is convenient when the recording sheet is brought into close contact with the recording sheet.

ものでもよい。 FIG. 2 shows an example of the configuration of a magnetic recording section for perpendicularly magnetizing the magnetic recording layer of the magnetic recording body 1 in accordance with a signal. In FIGS. 1 and 2, numeral 3 denotes a magnetic recording head, which consists of a thin magnetic core punched into a predetermined shape, and is constructed by stacking a plurality of them according to the number of recording points. The magnetic core of each magnetic recording head 3 has a magnetizing coil 3.
Each A is wound independently. The tip of the recording section 3B of the magnetic recording head 3 has a surface area determined by the size of the pattern of information to be recorded, and has a square size of 0.1 mm to 0.01 mm. In addition, the surface of the closed magnetic field section 3C facing the non-magnetic recording sheet 2 has a much larger surface area than the recording section 3B, reducing the density of the magnetic field that crosses this and allowing the field to pass under the closed magnetic field section 3C. This is to make the magnetization of the magnetic recording layer of the magnetic recording body 1 extremely small. Reference numeral 4 denotes a closed magnetic field forming member made of a magnetic material, and is installed facing the magnetic recording head 3 with the magnetic recording body 1 and the non-magnetic recording sheet 2 interposed therebetween. The non-magnetic layer 4A of the closed magnetic field forming member 4 transfers the magnetic field within the magnetic recording head 3 and the closed magnetic field forming member 4 generated by the electric signal applied to the magnetizing coil 3A into the magnetic recording layer of the magnetic recording body 1. This is a magnetic field deflection layer that is vertically aligned. Reference numeral 5 denotes a developing section, and the developing toner used in the dry developing method is, for example, toner made from magnetic powder such as CrO 2 , Fe 2 O 3 , Fe 2 O 4 , or the like. The preferred powder size of this magnetic toner is 0.1 μm to 10 μm and a synthetic resin material such as acrylic resin or vinyl resin is kneaded with a suitable solvent such as toluene, MEK, or ethyl acetate, and then centrifugally dried. It can be powdered, or it can be dried and then ground to powder. Further, as the dry developing method, a known method such as a magnetic brush method, a cascade method, a powder cloud method, etc. is used as appropriate. Here, as for the liquid development method, a known method such as a dipping method, a roll method, a mist method, etc. is used as appropriate. 6 is a fixing section, and a known fixing method is used. 7 is a demagnetizing head for demagnetizing the magnetic latent image recorded on the magnetic recording layer of the magnetic recording body 1, and 8 is a demagnetizing head for demagnetizing the magnetic latent image recorded on the magnetic recording layer of the magnetic recording body 1; This is a close contact device that allows for closer contact. This contact device 8 is not limited to the above-mentioned means, but any means may be used as long as it brings the magnetic recording layer of the magnetic recording body 1 and the non-magnetic recording sheet 2 into close contact.

に前記情報の磁気潜像を記録する。 When the magnetic recording body 1 is moved (or rotated) by a drive device (not shown), the non-magnetic recording body 2 is brought into close contact with the magnetic recording layer of the magnetic recording body 1 by the contact device 8. , passes between the magnetic recording head 3 and the closed magnetic field forming member 4. At this time, when a current is applied to the magnetizing coil 3A of the magnetic recording head 3, a closed magnetic field is generated between the magnetic recording head 3 and the closed magnetic field forming member 4, as shown by the dotted line in FIG. The magnetic recording layer of the magnetic recording body 1 is magnetized.
Furthermore, when the current is not applied to the magnetizing coil 3, a magnetic field as shown by the dotted line in FIG. 2 is not generated, so that the magnetic recording layer of the magnetic recording body 1 is not magnetized. That is, a magnetic latent image of the information is recorded in the magnetic recording layer of the magnetic recording body 1 by controlling whether or not to apply current to the magnetizing coil 3 in accordance with a signal corresponding to the information desired to be printed.
