ABSTRACT:
A recording medium comprises a recording layer formed on a substrate. The recording layer comprises a solid solution of a guest compound in a matrix polymer. The guest compound, such as a para-di-substituted benzene derivative, has a substantial second order micro-nonlinear optical constant .beta. but shows substantially no nonlinear optical effect in its crystalline form. The matrix polymer is preferably a polyoxyalkylene. A part of the recording layer is caused to have a nonlinear optical effect when it is supplied with a combination of an external field such as an electric or magnetic field and heating followed by cooling for solidification, and is caused to lose its nonlinear optical effect when it is subjected to heating followed by cooling for solidification in the absence of such an external field.
