More Information
Summary:A data storage device comprises a first substrate and a second substrate, wherein at least the first substrate has defined thereon a plurality of pits and lands covered by a reflective material; and a bonding layer between the first and second substrates including a reactive agent that interferes with the passage of light in response to predetermined stimulus. In another embodiment, an optically-readable storage media, comprises a substrate having encoded data stored thereon, a reactive agent that, in response to predetermined stimulus, interferes with the passage of light of a predetermined frequency range, and a second reactive agent that, in response to predetermined stimulus, degrades the readability of the encoded data.
