摘要： PROBLEM TO BE SOLVED: To enable the formation of a display record pattern which can be easily erased and maintained as a high-quality image and is free from an oozing- out phenomenon. SOLUTION: This recording method is to cause a material of colorless solid at normal temperature having a close refractive index to that of a material forming a porous layer to move through a display recording medium consisting of the porous layer with a space formed on a support base, by heating and melting the material from the outside of the display recording medium and filling a space in the porous layer with the molten material to form a display recording pattern. This display record pattern can be erased by vaporizing the material of colorless solid at normal temperature which is packed in the space by the heating of the display recording medium.
