PURPOSE:To obtain an extremely thin type optical information recording carrier by subjecting a photoresist surface of a laminate of a base material, light absorptive layer and photoresist to pattern exposing and light emitting and converting the information recording thereof according to an emission intensity distribution and reproducing said information record. CONSTITUTION:An illuminating luminous flux from the outside is projected onto the optical information recording carrier formed by forming a luminous body pattern 6 on the light absorptive layer 2 laminated and disposed on the base material 1 and laminating a transparent base material 7 via an adhesive layer 8 on the pattern to apply the energy to the pattern 6 so that the pattern emits light. The information record recorded by concn. distribution of the pattern 6 is converted to the emission intensity distribution to reproduced the above- mentioned information record. The reflected light of the light illuminated to the recording carrier does not directly act as the information reading light according to the above-mentioned constitution and, therefore, the resistance to the inclination of a card, etc., and the misalignment of an optical system, etc., is obtd. Since the recording medium constituting the information recording face is constituted of the concn. distribution of the luminous body which emits light according to the energy of the light projected from the outside, the production of the carrier is easy and inexpensive. The reduction in the thickness and size of the entire part of the information reading out system is facilitated. |
