Abstract: PURPOSE:To obtain a flexible and thin sheet-like recording body capable of writing and erasing information reversibly, by a method wherein a layer, in which magnetic particles are dispersed in a light-dispersible medium having a fluidity varying with a temperature, is constituted as a heat-sensitive magnetic layer. CONSTITUTION:A heat-sensitive magnetic recording body is made by laminating heat-sensitive magnetic layers and light-permeable protecting layers sequentially on a base. As the heat-sensitive magnetic layer, a light-dispersible medium having a fluidity varying with a temperature, such as a layer in which, for example, magnetic particles are dispersed in a thermoplastic or thermomelting substance, is used. When heat and a magnetic field are applied simultaneously, the magnetic particles move and writing and erasing of any information may be effected reversibly. A thermoplastic resin such as polyethylene, polyacrylic acid, copolymer of ethylene and vinyl acetate, or copolymer of ethylene and maleic acid is suitable as the light- dispersible medium. Specifically, n-paraffin having a melting point of 50-200 deg.C is one of the most suitable medium for this purpose.
