Can DVDs have laser rot?
Laserdiscs are subject to what’s commonly called laser rot: the deterioration of the aluminum layer that can occur if the seal between disc sides is broken. The large size of laserdiscs makes them flexible, thus allowing more movement along the bond between sides. DVDs are much more rigid. Also, DVDs are molded from polycarbonate, which absorbs about ten times less moisture than the PMMA used for laserdiscs. It’s too early to know for sure, but DVD’s will probably have few or no laser rot problems.
