Summary:PURPOSE: To obtain an information recording medium having excellent repeatability of recording/erasing, display contrast and preservable stability by using high-polymer liquid crystals having a specific mol.wt. distribution for the recording layer of this information recording medium. CONSTITUTION: This information recording medium is obtd. by incorporating the high-polymer liquid crystals of the mol.wt. distribution of Mw/Mn<=4.0 into the recording layer of the information recording medium formed by providing the surface of a base material with the recording layer. The high-polymer liquid crystals may be a layer formed by crosslinking the liquid crystals after molding. The high-polymer liquid crystals are preferably a copolymer of a mesogen monomer and a non-mesogen monomer.
