ABSTRACT:
An optically anisotropic recording medium and a method of recording and erasing method using the recording medium are disclosed, which comprises the steps of applying heat or light to the recording medium which comprises a recording layer made of optically anisotropic organic thin-film-shaped crystals to raise the temperature of an organic material or which comprises the optically anisotropic organic thin-film-shaped crystals to a recording temperature at which the crystals are fused, performing partial changing of the crystalline state of the crystals by rapidly cooling the recording layer, thereby recording information in the recording layer; and heating the recording layer to an erasing temperature which is lower than the recording temperature, at which the crystals are not fused, but the molecules thereof can be thermally moved.
