[rescue] cd-rom rot

[Lionel Peterson]

I attended a tech open house at a previous employer back around the late 80s,
they were talking about the impermanence of CD-ROMs as long-term storage
mediums back then. It was described as an unknown but certain issue.

The employer was a major oil company, and they had some record retention
requirements that well-exceeded the anticipated shelf life of CDs, so they
stuck with tape and were investigating optical storage options.
