Limited play data storage media and method for limiting access to data thereon |
摘要 |
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� C. wherein the second substrate is between the reactive layer and a laser incident surface. |
