Abstract
An optical disk with an embedded security device, or wafer, is presented. The security device includes security features that enable the identification of genuine optical disks versus counterfeit optical disks. Methods for creating optical disks embedded with security devices are also presented. An optical disk having a cavity formed on a surface to receive a security device is created. A special mold with a raised platform creates the cavity on the optical disk. The security device is located in the cavity of the optical disk and bonded to the optical disk.
Claims20
A method for creating a counterfeit-resistant optical disk, comprising:
- obtaining an optical disk having a cavity formed on a surface of the optical disk;
- placing a security device into the cavity of the optical disk, wherein the security device includes a security feature for identifying the optical disk as a non-counterfeited optical disk;
- and
- bonding the security device to the optical disk.
A method for creating a counterfeit-resistant optical disk, comprising:
- creating an optical disk having a cavity formed on a surface of a non-storage area of the optical disk;
- placing a security device into the cavity of the optical disk;
- and
- bonding the security device to the optical disk.
