LIMITED PLAY OPTICAL DEVICES WITH INTERSTITIAL REACTIVE LAYER AND METHODS OF MAKING SAME

摘要

Methods and apparatus are provided for making an optically readable storage media in which the reading beam passes through a bonding layer configured wi th a reactive material that transforms from an optically transparent state to a n optically opaque state after exposure to a predefined stimulus, thereby inhibiting access to the data encoded on the optically readable storage medi a. The method includes steps of synthesizing a blocked dye combining the blocke d 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 readabl e 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 makin g an optically readable storage media with at least two mechanisms for limitin g access to the encoded data of the optically readable storage media.
