Digital BW, The Print

I'm not taking sides on the film/digital debate, but whether a CD 
will last 300 years really isn't the issue.  The issue is whether 
anyone will have a CD reader in 20 years.  Consider that 8 track 
tapes, 78 rpm records and 8" floppies are already a problem.  It 
really doesn't matter if it is digital or analog; the issue is the 
technology required to retrieve the information and the availability 
of that technology.

I know a large research library that has been scanning all its art 
for years.  They recently started archiving to DVD, and at the same 
time are converting all their earlier CD archives to DVD.  They 
figure they will go through this process -- converting their entire 
archive to a newer technology -- every ten years.

I also have contacts within the film/movie studio world.  They know 
how to save film for 50 or 100 years.  They are still scratching 
their heads about digital.
