[time-nuts] Archiving Data

Hi Perry:

It's a real problem.  Modern movies are edited and in some cases sent to 
theaters as digital data.  Last I heard the specified lifetime of data 
on a hard disk is 10 years (although probably much longer).  It's very 
expensive to transfer data every ten years to a new drive.  Modern movie 
prints are archival, but some earlier color movies are not.  I've heard 
that a small number of CD - DVD brands/models are archival quality.

Have Fun,

Brooke Clarke
