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. Layer-wise, the tag is either sandwiched between the
two substrates or alternatively embedded within one of the two substrates. In the
case where the tag is sandwiched between first and second substrates, a bonding
layer occupies a space radially outward from the tag. The bonding layer holds the
first and second substrates together thereby forming the secure disc.
