Abstract

PURPOSE:To make a titled medium applicable as a display device of an energy economization type by providing a magnetic material film for recording magnetism and a film contg. a colloidal soln. of a magnetic material which is disposed adjacently to said magnetic material film and is used for visualizing the magnetized pattern recorded to the magnetic material film. CONSTITUTION:This highly flexible sheet-like medium for recording and displaying information is constituted by sealing the colloidal soln. 4 of the magnetic material between a protective film 2 and protective film 5 facing each other via a spacer 3 and further bringing the magnetic material film 1 into tight contact with the protective film 2. The magnetic material film1 is uniformly magnetized in one direction when such medium passes along a magnet 6 for erasing while contacting with the top surface thereof. The part of the pattern to be recorded and displayed is magnetized in the direction opposite from the direction where the film is previously magnetized by the magnet 6 when said medium passes along a magnetic head group 7 for writing while contacting with the top surface thereof. The pulverous magnetic material particles in the soln. 4 adjacent to the film 1 via the film 2 are thereby disposed to comply with the magnetized condition of the film 1, by which the pattern written to the film 1 is displayed.

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、情報の記録衣示技術に関し、特に新規な視覚
化磁気記録媒体に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to information recording and display technology, and particularly to a novel visualization magnetic recording medium.

〔従来の技術〕[Conventional technology]

従来、情報の書き換え可能な記録方式としては磁気記録
方式が用いられ、またＴＰＴ報の視認可能な形態での記

ことが通例であった。。Conventionally, a magnetic recording method has been used as a rewritable recording method for information, and a printing method on paper has been used as a method for recording and storing TPT information in a visible form. Ta. .

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

上述した従来の技術において、磁気記録方式については
、記録の書き換えは比較的容易に行なえるが、その記録

を目で見て利用することはほとんど不可能であった。In the conventional technology described above, it is relatively easy to rewrite records using the magnetic recording method, but in order to directly view the recorded contents, it is necessary to use a device containing a colloidal solution of magnetic material to record the information. The magnetization pattern must be read by contacting the magnetic recording medium, and since the recorded content is also in binary form, it is almost impossible to directly view and use the recorded content. there were.

他方、紙への印刷記録方式については、記録内容はその
まま直接目で見て利用でき、保存も可能ではあるが、書

用のための情報の記録に対しては、再使用不能な用済の
紙が生じるという欠点があった。On the other hand, with the paper printing method, the recorded contents can be viewed directly and used as is, and can be stored, but since they cannot be rewritten, the information is for temporary use and does not need to be stored. However, this method had the drawback of producing waste paper that could not be reused.

is enclosed between a protective film 2 and a protective film 5 facing each other with a spacer 3 in between, and a large flexible sheet-like information recording/displaying medium having a structure in which the exposed magnetic film 1 is in close contact with the protective film 2. As shown in FIG. 2, when this medium passes through the upper surface of the erasing magnet 6 while being in contact with it, the magnetic film 1 is uniformly magnetized in one direction, and furthermore, the magnetic film 1 is magnetized in one direction. When passing through the upper surface in contact with each other, if the part of the pattern to be recorded or displayed is magnetized in the opposite direction to the direction in which it was first magnetized by the erasing magnet 6, the magnetic film 1 and the protective film 2 are Since the magnetic fine particles in the magnetic colloidal solution 4 adjacent to each other are arranged according to the magnetization state in the magnetic film 1, the pattern written on the magnetic film 1 is displayed.[Effect of the Invention] As explained above, the visualization magnetic recording medium of the present invention has
When patterns such as letters and figures are magnetically recorded on a magnetic film on one side of a medium using a magnetic head or other method, the recorded pattern can be seen from the other side.
In addition, since the recorded contents can be magnetically rewritten, it can be easily reused, and it can also be easily made flexible, so it is similar to recording paper for computer system output devices and facsimile machine recording paper. By applying this as a storage space, it is possible to save paper storage space and output information quickly and quietly.In addition, by utilizing the fact that no energy is required to maintain records, it is possible to use energy-saving types in displays, etc. It can be applied as a display device.
