METHOD OF PRODUCING AN OPTICAL RECORDING CARD

摘要

This optical recording card (1) includes optical recording medium (4) which is formed with optical information patterns each of which has an optical reflective layer and informations stored in the optical recording card (1) can be read out in dependence on difference in optical reflectivity of the optical information pattern. The optical recording card (1) is produced by way of the steps of forming an optical reflective layer on a continuous base film having large area and then die cutting the assembly of optical reflective layer and base film into a large number of optical recording cards (1) having required dimensions in such a state that the optical recording medium (4) is held between a card base and a protective sheet (3).
