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.
