hmm ... what do you want from an archive? if, like many archives, you want
something in a format that can be played repeatedly then most analogue formats
are no good, they usually suffer a little each time they are played. You can
keep working copies and ones you only touch rarely to try to get around this.
But most analogue formats change over time anyway ... the colours in an analogue
film when it was new are a long way from the colours you will see when you
project it some years later, even if the film has been untouched since then ...
chemical reactions continue even without playing the film. Magnetic tape with
audio or video decays and becomes unplayable over time. Analogue copies are
never quite exact, so duplicating from time to time onto fresh media doesn't
solve this in the way it can with digital versions ... with digital it is only
the original transcription into the digital format that has a certain
generational loss. Using grooves cut in a medium depends on the stability of the
Analogue certainly is no help in regard to the player problem ... any digital or
analogue format requires a working player to access it easily, and both can be
extracted in some way and the original recreated if the format is properly known
and the marks are still readable in some way. But digital is much more tolerant
of the inevitable noise age adds to media, the yes-no nature of the bits means
it is easier to reconstruct accurately and means the gaps are known gaps and
strategies can be used to fill them in.
Many accurate copies widely distributed in a variety of formats is the best
strategy for satisfying some desire for a kind of immortality, and that copying
is much more feasible in a digital format.
There are a lot of reasons archives use digital formats for preservation, and
there are particular formats with matching hardware encoders, full public
documentation etc that are often preferred.
But the question opened up here is what a copy of some work really is, and
really nothing can preserve a work with all its context, and out of context it
is in many ways a different work.
