Methods and apparatus are provided for making an optically readable storage
media in which the reading beam passes through a bonding layer configured with
a reactive material that transforms from an optically transparent state to an optically
opaque state after exposure to a predefined stimulus, thereby inhibiting access
to the data encoded on the optically readable storage media. The method includes
steps of synthesizing a blocked dye combining the blocked dye with a carrier material
curing the resultant combination deblocking the dye to produce a reduced dye in
the resultant bonding layer exposing the optically readable storage media with
the reactive material in its bonding layer to a predetermined stimulus. In a further
aspect of the present invention methods and apparatus are provided for making an
optically readable storage media wherein the reading light passes through the bonding
layer and the data encoded information is encoded on the L1 substrate. In
yet another aspect of the present invention methods and apparatus are provided
for making an optically readable storage media with at least two mechanisms for
limiting access to the encoded data of the optically readable storage media.
