摘要:
A system for selectively enabling or disabling an optical device, such as an optical disc, includes an optical blocking material bonded or otherwise integrated into the optical device. In a specific embodiment, the optical blocking material includes a dye, such as an energy-sensitive dye. The optical blocking material is initially applied to the optical device during production using a spin coating or other suitable technique. An area of the optical device that will prevent a function of the device is then masked, and sufficient energy is applied to the unmasked area to activate the optical blocking material of the unmasked area while leaving the masked area unactivated. In a specific embodiment, the masked area corresponds with a lead-in area of an optical disc. The optical blocking material of the masked area remains non-transparent to disable the optical device until a second application of energy at a retail location.
