Abstract
There are provided optical data storage media and methods of optical data storage using the same. The optical data storage media comprises a non-linear sensitizer capable of absorbing actinic radiation to cause upper triplet energy transfer to a reactant that undergoes change upon triplet excitation. The refractive index change (Δn) of the medium is at least about 0.005, or even at least about 0.05.
