I agree that vinyl should be carefully stored after transcription, and so
should the CD-Rs. However, hard drives aren't reliable means of archiving,
either. Hard drives can definately fail while being stored.

This method of storing data is known to last for dozens of years, by
means
of practical example and acellerated life testing.

I know of no medium that hasn't failed for the Smithsonian.

I searched for credible references to confirm this, and found none. Please
provide a link.

Caution is always a good thing.

I have never worked with media that was more prone to sonic degradation
than
vinyl and analog tape.

I know of no commercial CD or DVD product that uses any substrate other
than
polycarbonate.

The gold standard for recordable CD and DVD meida is usually given as
being
Taiyo Yuden. Their products are widely available for reasonable prices.
