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