Limited play optical devices with interstitial reactive layer and methods of making same

A data storage device, comprising:

• 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;
• a bonding layer between the first and second substrates;
• a reactive agent that, in response to predetermined stimulus, interferes with the passage of light of a predetermined frequency range;
• and
• material that interferes with the passage of light of a second predetermined frequency range through the material.

A data storage device, comprising:

• 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, wherein the reflective properties of the reflective material deteriorate in response to predetermined stimulus;
• a bonding layer between the first and second substrates;
• and
• a reactive agent that, in response to predetermined stimulus, interferes with the passage of light of a predetermined frequency range.

An optically-readable storage media, comprising

• 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, in response to predetermined stimulus, degrades the readability of the encoded data.
