<DIV>Every year computers have more horsepower.... who knows the state of the
art just 10 years from now!?</DIV>
<DIV>and in 20 years even more dramatic. I remember 1965 learning punch cards
and plug boards.. by 1975 we had microprocessors by 1985 we
had some nice super computers 20 years... only 20
years...</DIV>
<DIV> </DIV>
<DIV>So... be patient.. if we do not have the affordable computing
power now perhaps we have only 5 to 10 years to wait!</DIV>

<DIV>You know a lot more about the theory than I, but that's kind of why I
figured that a scanner would be needed rather than a stationary head. Even if
you could use stationary heads, you would need many, all with different head
gaps for the various frequencies.</DIV>
<DIV><BR></DIV>
<DIV>A single-head scanner might be able to create an image of all of the
frequencies and their location on the tape. You can run the linear speed of
the tape at anything, but the scanner (head wheel) would run at the optimal
speed. </DIV>
<DIV><BR></DIV>
<DIV>You would need some powerful software that would look at the physical
layout of the tracks and reconstruct, in a sense a virtual demod of the
signal. The reconstruction of that image into video sounds like a lot of work.
I see it as a way someone a hundred years from now might go about trying to
figure out what's on some tape and there are no longer a VTR to play it back
on.</DIV>

<DIV>A year or so ago I had mentioned to a person famous in the ASIC/FPGA
programming world that a Quad machine signal and transport system would be a
good project for her. She never wrote back, even though she was soliciting
ideas for projects.</DIV>

<DIV>Oh well,</DIV>
