ABSTRACT:
A high dielectric polymeric optical recording medium for recording information by heating the portions of the recording medium corresponding to the information to be recorded by being exposed to a beam of light, followed by the application of a reverse electric field to the recording medium, thereby selectively reversing the polarity of the heated portions in the recording medium, is disclosed, which comprises a high dielectric polymeric recording layer containing a high dielectric polymeric composition comprising a high dielectric polymeric material and a nonionic dye serving as a light-absorption agent which is compatible with or dispersible in the high dielectric polymeric material.
