You know, the thing is, it could be that the machines have moved out of
alignment subsequently, or that alignment that was out, was moving
further out of alignment. It would be worth checking? I would only fix
"one" machine to begin with, in case there are alignment problems,
which when corrected, make matters worse! for tapes that were recorded
on them, and currently are playing back "fine" on those same machines.
I would have to hear the tape to know whether it was drop out or
alignment problems. Without hearing it, I would say that generally, if
the tape is going along just fine, and then you hit a section where it
starts to make that horrible digital noise sound,
sssssssffffffffffeeeeeeeee, then, further along in the tape, it's fine
again, _probably_ that's a drop out, and not and alignment problem.
What to do about drop outs, I haven't heard. As I said before, an
analogue drop out is categorically not nearly as serious...If you find
anyone who knows how to get over the digital drop outs, let me know; I
would be interested as well :)
As far as alignment, I wonder if there are people who specialize in
moving the heads in and out of alignment in order to get the tapes to
play? What a gig!
When I used to work in broadcasting, often, it is true, one machine
would play back the tape where another one wouldn't. This still was
alignment problems. But if the alignment was severely out - tough luck,
and you couldn't get it to play back, unless you could find the
original machine - I wasn't always around to see if that _always_
worked, but more often than not, I heard it did; but these were tapes
that were recorded usually only a few weeks before being played back,
at best - not years - so the heads on the recording deck usually
couldn't have gone that far out in the meanwhile...
