Hm...interesting. This throws merry hob to most of
my ideas, since the creation of the master (basically,
a pitted metal disc formed from a photoresist-exposed
glass disc that is fitted into a die/injector) is carefully
described, and the compact discs are formed in the injector
using liquid that quickly hardens into polycarbonate
plastic. Perfect, to a point, duplicates.
It is far from clear whether they can be serialized afterwards.
Of course I should have suspected something along these lines anyway.
