Notice my two annuities in the list. I think it's imperative that
this be considered. You made a lot of good points in your recent post.
I fear that we have transcended stable media on the shelf, and I am
not sure we'll ever return.
At this point, my best guess for stable media are certain data tapes,
but they still need review...unless we decide to go back to shellac
as some wags at National Public Radio suggested a few years ago on
the first of April. Steve Smolian was even implicated in that effort.
I am not prepared to publish anything yet -- in fact, it appears that
much of the grunt work has been published already but in journals
obscure to media people -- but the more I research this, the more I
believe that tape is not forever, either.
I do tell people that digital archives do not react well to budget
interruptions. I'll go further to say that power interruptions can be
engineered around, but budget interruptions on the order of even a
few years can be catastrophic.
Karl's enthusiastic response to the first part of my conjecture is
great and we need more people talking about this. However, if we look
at current "best practices" of digitizing everything at 24/96, a TB
is roughly 1,000 track hours. Hence my call previously to consider
some bit reduction. My preference is 16/44.1, but other options are
available. 16/44.1 provides 3,000 track hours per TB and I think is
adequate for 1.88 and 3.75 in/s oral histories recorded on Wollensaks
and even Uhers, as well as cassettes recorded on most (non-top-end)
machines. So, my 100 TB store proposal would hold between 100,000 and
300,000 track hours or 50,000-150,000 hours of stereo material, minus
overhead for proxies and metadata.
Yes, they could/should be networked. My proposal for the Cal State
Fullerton project was to see three equal repositories for the state
of California, located in three geologically diverse regions,
connected by high-speed fibre optics. Replication software would be
running as well as background error checking. I still think this is a
good model for storage. I have replicated it here on a minor scale
with three stores, each 1.25 TB, and one is in a geographically
distinct area -- my neighbour's basement <smile>--connected by a
medium speed fibre optic link (100 Mb/s).
I continue to look into LTO tape, as I hear the prices have dropped
somewhat on drives. The tape cost has always been attractive.
Cheers,
Richard
