摘要： An optical media disk is treated with a light-sensitive material that impedes the ability of an optical media player from reading data stored on the disk. This light-sensitive material is a material changes phase upon exposure to one or more wavelengths of light. During the initial phase, the light-sensitive material will render the disk unreadable. After activation, however, the disk becomes readable by conventional optical media players. In this fashion, theft of yet-to-be-activated optical media is deterred.
