ABSTRACT:
Recording medium having islands of light-emitting material in regions formed between a transparent substrate, and a reflective layer disposed on one princpal surface thereof. The islands of light-emitting material are sensitive to illuminating light incident thereupon, and in response thereto, emit light having a different wavelength than said illuminating light. Reproducing apparatus separates an overall reflected light from the recording medium into first reflected light corresponding to a reflected scanning light, and second reflected light corresponding to emitted light from the light emitting material.
