Limited play data storage media and method for limiting access to data thereon

   
   

A limited play optical storage medium for data is provided in the present invention. The limited play optical storage medium for data comprises a first substrate; a reflective layer; a data layer disposed between said substrate and said reflective layer; a reactive layer comprising at least one carrier; and at least one reactive material; and an optically transparent second substrate with an oxygen permeability in a range between about 0.01 Barrers and about 1.35 Barrers at 25.degree. C. wherein the second substrate is between the reactive layer and a laser incident surface.

Un medio de almacenaje óptico limitado del juego para los datos se proporciona en la actual invención. El medio de almacenaje óptico limitado del juego para los datos abarca un primer substrato; una capa reflexiva; una capa de datos dispuso entre el substrato dicho y la capa reflexiva dicha; una capa reactiva que abarca por lo menos un portador; y por lo menos un material reactivo; y un segundo substrato ópticamente transparente con una permeabilidad del oxígeno en una gama entre cerca de 0.01 Barrers y Barrers cerca de 1.35 en 25.degree. C. en donde el segundo substrato está entre la capa reactiva y una superficie del incidente del laser.
