Security marking system and method for minimizing pirating of data on data media including compact discs and digital versatile discs

A method of marking a data disc product comprised of polycarbonate material and storing data thereon, the method used for tracking purposes to inhibit at least one of piracy, unauthorized access and unauthorized copying of the data stored on the data disc product, said method comprising the steps of:

• (a) introducing at least one predetermined tracing substance as a predetermined marking in the polycarbonate material of the data disc product in quantities that will not substantially adversely affect the readability of the data stored on the data disc product, wherein said introducing step (a) further comprises the step of introducing the at least one predetermined tracing substance as a security marking in the polycarbonate material including predetermined concentration amounts of at least one of an isotope, a plurality of isotopes and a plurality of stable isotopes;
• (b) manufacturing the data disc product with the at least one predetermined tracing substance introduced therein in said introducing step (a);
• (c) identifying by inspecting the data disc product the at least one tracing substance including the predetermined concentration amounts of the at least one of the isotope, the plurality of isotopes and the plurality of stable isotopes for tracking purposes to inhibit at least one of piracy, unauthorized access and unauthorized copying of the data stored on the data disc product;
• and
• wherein said identifying step further comprises using at least one of mass spectrometry, neutron absorption and neutron spectrometry techniques.
