ABSTRACT:
A recording medium having a recording layer comprising a polymer liquid crystal is used for multivalue recording by using at least two different liquid crystal phases at least two levels of locally different liquid crystal proportion, or thicknesswise difference in an optical variable, such as transmittance a reflectance, generally through controlled heating and cooling. In effecting the recording, two heating sources may suitably be used, one for imagewise heating and the other for supplemental heating.
