Hi Arthur
"operational lifetime of more than 1,000 overwrite or 1 million read cycles,
with an expected archival lifespan of well over 30 years"
"Based on accelerated ageing tests, the lifetime of TDK's CD-R REFLEX has
been computed to be well over 100 years. "
I am sure have seen in various places that RW is more delicate and has
shorter expected lifespan.
If you want to catch up some CD meda information try:
Of course if the 30 years is accurate you need not worry as no doubt at some
time in the next 10-20 years you will be able to transfer several hundred
CD's onto the latest mass archival storage media.
