- 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?
