1. A binary data recording medium, comprising:a substrate; a recording layer on the substrate, the recording layer comprising an organometallic transition metal complex, the transition metal complex absorbing light having a first wavelength; wherein the transition metal complex has a light-induced excited state, the excited state resulting in a reaction product in the recording layer which absorbs light having a second wavelength, the first and second wavelengths being different and where light absorption of the first wavelength is assigned a first value, and light absorption of the second wavelength is assigned a second value, the first and second values corresponding to binary code.
