Re: compact disc longevity



The following site has a lot of information and a lot of
links to other sites with information - from the industry
perspective. Most of the problems with short CDR life (and
short CD life) is in problems in manufacturing. A properly
manufactured archival quality CDR (yes, they are available)
should outlive you and your successors, by which time the
information would have been transferred to whatever data
storage system is current at the time, without degradation
of the quality of the data or audio. There will be more
permanent storage systems developed with "permanent"
hardware and software to read it! :-)
