Yep, depnding on various factors (heat, humidity, sunlight, dampness,
etc.) the dyes used on recordable CDs and DVDs is pretty hopeless,
especailly the cheaper ones. 

There is (was?) one drive which uses special discs and physically burns
them in the literal sense, and those should last a long time, although
no doubt have problems, just like properly press-manufactured CD / DVDs
can suffer from.

Hard drives can of course die as well, so you need to check them
occasionally. Plus there's the problem that the disc format may become
so obsolete that finding a device in, for example, 50 years time may be
near impossible. (Try finding anything in most shops that will read VHS
tapes now.)
