An optical recording medium is provided to coat chelate dye having azo based compounds and metallic ions on a recording layer so as to enhance absorbance of blue laser and heat stability. An optical recording medium has a recording layer. The recording layer includes chelate dye having more than two azo based compounds having at least one heterocyclic ring connected to an azo device, and more than two metallic ions. The metals are selected among a group I without hydrogen, a group II, a group III without boron, a group IV without carbon and silicon, and elements, Sb, Bi, and Po of groups VIII, V, VI, and VII.
