Abstract
An Electronic Article Surveillance (EAS) marker (10) is adapted for direct application to optically recorded media such as compact disks. CD-ROM's, laser disks, digital video disks, and the like. The marker includes a support sheet (12) and one or more marker elements (16, 18) which are positioned such that the mass distribution of the marker is symmetrically disposed about the center of the marker. This ensures that when the marker is properly positioned on the optically recorded media, the marker does not adversely affect the mechanical balance of the media.
