ABSTRACT:
A secure optical data disc comprising an electronic article surveillance tag embedded within a layered disc structure comprising first and second substrates is disclosed. The tag is placed within a non-readable zone (i.e., one that does not have data tracks) of the secure disc. To improve signal quality of the tag, the reflective metal layer thickness is minimized and discontinuities are introduced on the reflective metal layer. A first discontinuity separates a data track region of the disc from a mirror/ID band region. A second, radial discontinuity opens the mirror/ID band ring.
