[mou] FW: CD and DVD degradation

[Alt, Mark]

		This is a highly technical paper detailing how DVD's and
CD's, especially recordable media, have limited ages to be used for
archiving purposes. I am not sure anyone needs this level of detail, but
it is a fun read for a techie. I may resort to keeping my DVD films in a
freezer when I am not using them. 25 years from now, no one else will
have any that work. Any archival records the MOU is looking at should
take this into consideration - we should buy these gold alloy disks and
have copies for backup.
