ABSTRACT OF THE DISCLOSURE Provided is an optical data storage medium comprising an organic information layer having a reflectivity of at least 20%. Moreover, the material of which the information layer is comprised exhibits good amorphous film forming characteristics and is readily solvent castable. The medium can also be erasable. The information layer comprises a chromophore composition which can be comprised of a chromophore or chromophore/polymer combination. Its high reflectivity elimi- nates the need for a metallic reflective layer in addition to the information layer, or the need for any anti-reflective structure. Thus, the structure of the medium is simplified. As well, the amorphous film-forming characteristics of the chromo- phore composition allow for ready manufacture of the medium.
