7. A method for labeling the data side of an optical disc, the method comprising:
-
a) providing a data layer on said data side, said data layer being writable or readable with radiation at a first wavelength;
b) providing an imaging layer on said data layer; and
c) applying a laser imagewise to the imaging layer so as to produce a mark that is substantially transparent to radiation at said first wavelength. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method manufacturing an optical disc, comprising:
-
a) providing a substrate;
b) providing a data layer on said substrate, said data layer defining a data side of the disc and being writable or readable with radiation at a first wavelength;
c) providing an imaging layer on said data layer, said imaging layer including color-forming agents that produce visible marks upon irradiation at a second wavelength. - View Dependent Claims (14, 15, 16, 17)
