摘要:
An information disk has a disk structure with a metalized data storage area. A radio frequency identification processor that is activatable by light, such as laser light, is coupled to the disk structure to prevent copying of copyrighted or otherwise secured data, and to prevent unauthorized use of the information disk. The processor may be positioned at a variety of locations on the information disk, including in the inner non-conductive area, and the outer non-conductive ring, as well as within the metalized data storage area. A process for enabling an information disk with an RFID processor includes providing a disk structure having a metalized data storage area, and positioning a short wavelength electromagnetic light activated radio frequency identification processor on the disk structure.
