Abstract
An optical disc has a first plate, a second plate adhered to the first plate, and an optically-activated colorant disposed between the first and second plates.
Claims20
An optical disc, comprising:
- a first plate;
- a second plate adhered to said first plate;
- and
- an optically-activated colorant disposed between said first and second plates;
- wherein said optically-activated colorant forms at least a portion of an adhesive layer adhering said first and second plates.
2 more elements
A method of fabricating an optical disc, said method comprising:
- providing a first plate that is substantially transparent;
- providing a second plate having a data storage medium;
- and
- providing an optically-activated colorant between said first and second plates.
1 more element
A method of labeling an optical disc, said method comprising:
- providing an optical disc having an optically-activated colorant disposed between first and second plates, said plates being adhered to each other;
- selectively directing a laser beam from said laser source onto said optically-activated colorant to visibly alter said colorant.
