Note: Presents
the complications in archiving that have taken place with the advent of
digital audio recording technology, most notably incompatibility of systems
and/or media. Presents comments on analog tapes from John Matarazzo, manager
of technical services for Sony, concerning binder breakdown, crystallizing or
oxidizing of lubricants, and treatment resulting in temporary stability in
order to make working copies; continues with uncertainty of how well digital
tapes store and critical nature of temperature and humidity in storage, with
information on metal evaporated tape, with some of advantages of optical
recording technology, that Open Media Framework (OMF) is addressing problem
of incompatibility and back up systems. "The requirements of OMF are
that we continually keep it backwardly compatible so, as we extend the
capabilities in the file format and the specification, we will continue to
support the things that were in there originally. That means that you can
never have an OMF file that you can't go back to and open and process with
the capabilities that you have at that time."

the performance characteristics of the cited Ampex product; in doing so,
includes the strongest statement yet from a manufacturer concerning use of
R-DAT as an archival medium: "Ampex's position about archiving valuable
source programming to R-DAT is simple. We do not recommend it." They,
then, give three reasons why it is not advocated: retrievability of damaged
analog vs. total loss of digital data; future access to recorders and lack of
experience with media and systems; and doubtful interchangability of tape and
machines.

problem of deteriorating sound recording tape, result of which is that the
tapes are very difficult to run and may, in serious cases, jam in the
recorder. The cause is thought to be the deterioration of the polyurethane
binder used to hold the magnetic material onto the tape base, probably caused
by hydrolysis of the polyurethane brought about by atmospheric moisture
adsorbed onto the tape surface. A method for temporarily reducing the problem
so that copy recordings can be made is described.
