I believe that the Council on Library and Information Resources will be
issuing a report on the shelflife of digital media in the near future (if
they have not already): http://www.clir.org.

delamination, where the layers of the disc separate. Symptoms of the rot
include picture break-up and freezing at a specific place on the disk. The
