Re: [ARSCLIST] Adhesives and Disk Labels



It would be helpful if anecdotal claims of disaster by Mr. Warren could
be substantiated. Contrary experience at Media Sciences indicates that
CD-R discs are useful for archival storage provided that care is taken
regarding media, writer, software, handling, and storage conditions.

This is true for all archival media. Poor processes lead to poor
results, while proper processes lead to good results. CD-R discs are
advantageous for three reasons. First, they store in a digital format
complete with powerful error correction information. Second, information
retrieval does not require physical contact with the information layer.
Third, storage in jewel cases avoids contact with the information layer,
unlike film or tape. Care must always be taken not to damage the fragile
protective layer on the label side.

Results of our scientific investigations, together with other
information, are published on our web site: http://www.mscience.com/
