First Claim
1. An optical media comprising:
- a substrate, wherein said substrate includes information encoding features encoded therein;
a reactive layer, wherein said reactive layer transforms from a substantially transparent state to a state that interferes with the passage of light in response to predefined stimulus, said reactive layer comprising;
a reactive material, wherein said reactive material has a first state that is substantially unreactive with said predefined stimulus; and
a second state that is substantially reactive with said predefined stimulus.

Abstract
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.
