Umm, this last statement is dependent on how long you leave a magnetic disc
beside a montior or in the sun. If you do neither, and store the disc out of 
harm's way, then I'd almost say the optical disc would decay (slightly) faster 
(dust particles get in the grooves (altering the defractive properties of the 
medium) and the plastic cracks with old age e.t.c...)

Has anyone done any experiments to determine which decays faster?
