Steve,

It is Jim Lindner's (the person that created the company Vidipax)

Hmmm.  Maybe you know.  I believe I saw a posting, now lost, that LOC
had an 
outside vendor copying their tapes en masse using an automated system. 
Could you possibly supply a reference or, better yet, a web address?

Those fantasies, at least, are becoming reality as we speak! Researchers
at 
Lawrence Berkeley National Laboratory, in a project in collaboration
with 
the Preservation Directorate of the Library of Congress, have developed
an 
3D optical imaging technology whereby the computer can create an actual 
playback from the optical image of a gramophone disk. This work is still

under further development, but the technology has been demonstrated. It
also 
should work for similar recordings; research and development plans
include 
work on cylinder recordings.
With regard to magnetic tape, research at the National Institute for 
Standards and Technology in Denver have developed magneto resistance
imaging 
sensors that image the magnetization on the tape and thus allow
non-contact 
reading of the recording. Again, this work is still under further 
development, but the practical feasibility has been demonstrated.

This is great food for future-thinking - does anyone think it will
eventually become possible to make an image scan of a disc and have the
computer read it, in the way a scanner and OCR can turn documents into
type or ASCII code? And eventually magnetic tape might be read, the way
we used to use chemicals to make magnetic patterns visible? I would
think it was easily possible given advanced anough computers and
software...

After all, I invented (in my imagination only!) memory chip delivery of
music when I was 14 in the 60s... now look at us... if only I'd had the
skills to manifest it then!

Fantasy becomes reality someday...
