It actually takes a metal class tape to store digital data on, and even on
these you will notice that DAT occasionally will have glitches and it
happens more often on digital video tapes (more with the picture than the
sound because it's harder to correct, and you are more likely to record this
in an environment with much motion.) and most floppies stuff up pretty
easily. Now, obviously more durable media such as CDs and MDs don't
experience errors that much thus the higher quality the media the more
likely it is that the reproduction will match the orriginal. If you took a
bunch of cheap minidiscs and continued using them until you had a few
glitches, and then repeated the experiment using higher quality discs, you
would probably find that it would take longer for the higher quality discs
to produce glitches.
