Zusammenfassung:	The present disclosure relates to a limited play optical storage media and a method for limiting access to data thereon. This storage media comprises: an optically transparent substrate; a reflective layer; a data storage layer disposed between said substrate and said reflective layer; an oxygen penetrable UV coating disposed on a side of said substrate opposite said data storage layer; and a reactive layer disposed between said UV coating and said substrate, said reactive layer having an initial percent reflectivity of about 50% or greater and a subsequent percent reflectivity of about 45% or less.
