Optical storage media with embedded security device
First Claim
1. A method for creating a counterfeit-resistant optical disk, comprising:
- positioning a security device in an optical disk mold, wherein the security device includes a spacing device attached to a surface of the security device such that the security device is prevented from being embedded flush with a surface of the formed optical disk;
closing the optical disk mold; and
forming an optical disk in the optical disk mold, thereby embedding the security device in the formed optical disk.

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. 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.
