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.
Un marqueur (10) de surveillance électronique d'articles (SEA) est adapté pour s'appliquer directement à des supports d'enregistrement optiques tels que des disques compacts, des CD-ROM, des disques à laser, des disques vidéo numériques et autres. Le marqueur comprend une feuille de support (12) et un ou plusieurs éléments marqueurs (16, 18) qui sont positionnés de sorte que la distribution de la masse du marqueur est disposée symétriquement autour du centre du marqueur. De cette manière, on s'assure que, lorsque le marqueur est positionné correctement sur le support d'enregistrement optique, il n'affecte pas l'équilibre mécanique du support d'enregistrement optique.
