From our tests certain CDRs burned on quality burner such as Plextor provide
much better results than any DAT tape. Data .wav CDRs are possibly the best
way to archive as we see it, while audio CDRs are used for access only.
The data CDRs provide easy storage option and the "migration" to other
systems is hassle free.
Aging tests I have seen show over 100 years reliability in a air controlled
storage and this is fine for me right now. The oldest CDs we have are 20
real years old now - they all play.
