You'll notice the Ampex used a moving pinch roller path with
resulting omega wrap around the drum, while the IVC used a fixed

<div>Don - Well if we never getting it
working that is ok too as we have an Ampex
camera that is a nice match for it... the
TelePrompTer 1 inch tape was supposedly
done on a IVC so we will try that. </div>
<div>If it works that is great as we have no
budget for outside services to convert it!
So fingers are crossed! </div>

<div><font size="3">I agree with many of
the comments on this thread, and to be
sure, the answer to Ed's question
comes with many qualifiers. The
primary reason that we use VPR-7900's
for recovery of Type-A tapes is their
ability to handle all three variants
of the format's carrier frequencies.
I believe the 5100 is low band only
which was intended only for black and
white, but since the Ampex format was
direct record, you can still recover
color from the lowband tapes if they
contain color material. Obviously not
the best situation, but possible.
Tapes recorded in hi-band or
very-high-band will not reproduce
properly on a low-band machine.</font></div>
<div> </div>
<div><font size="3">Regarding interchange,
there's no doubt that the movable
guides were a bad design. However,
our experience has shown that many of
the interchange problems were the
result of incorrect adjustment of the
machines more often than "naturally
occurring" changes in the guide path.
Because this was originally a
"non-broadcast" format, much of its
use was in educational or industrial
applications, and generally with
un-trained operators. My favorite
example was a tape we received from a
large university. It begins with no
video, but on the audio track, you
hear "Hey Bill, how do you work this
thing?". Then the machine was
obviously stopped, and when it was
re-started, there was video, recorded
with a setup level of about 70%! </font></div>
<div> </div>
<div><font size="3">The challenges of
recovering Type-A tapes can be
significant, and we have even done
custom modifications when required for
special problems if the budget was
available. When the tapes are good,
the quality, especially from the VHB
tapes can be excellent, but that is
certainly the exception rather than
the rule. Bottom line is, we're
talking about a format developed in
the mid 60's, and a lot has changed
since then!</font></div>
