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. A security device is placed on the center pin of an open
mold before the optical disk is formed. Alternatively, 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. As a further alternative, two optical platters, each having
a complementary cavity to accommodate a security device are created using
a special mold having a raised platform. The security device is inserted
into the complementary cavities and the optical platters and security
device are bonded together.
