[ARSCLIST] CDR media longevity

[Jos Van Dyck <jos.van.dyck@xxxxx>]

We are transferring archive radio transcription disks and tapes to CDR
for digital archiving.

Which media would you recommend for real time (1x) recording, e.g.
with Sony CDR-W66?

We tried MAM-E Gold Prostudio, but BLER, E22, E32 (measured with
StageTech EC2) are unacceptable.

For archives, longevity is of paramount importance.
However, after a few years some CDRs are showing increasing error
rates, and some tracks become unreadable.
(e.g. BASF by Ricoh, BASF by Kodak, Verbatim by TDK).

Is systematic error checking of the whole archive needed? At what
intervals?

What other digital storage media is more reliable than CDR (computer
tapes, hard disks)?
What types of streamer tapes (AIT, DLT, SDLT, LTO)?
