Abstract
An optical recording media includes a recording film, and a stacked film of at least two dielectric films A and B formed on at least one surface of the recording film. Each of the dielectric films A and B contains as a main component a compound selected from the group consisting of an inorganic oxide, an inorganic nitride, an inorganic sulfide and an inorganic fluoride or a mixture thereof, and the refractive indexes nA and nB of the dielectric films A and B satisfy the following relationship: (nA−nB)/(nA+nB)≦0.05.
