<DIV>The tape was reqular quad tape. The same principles that Bill
described became the standard for duplicating consumer VHS tapes. If you
ever bought a pre-recorded VHS tape, it was probably done on this type
system. Below are a number of pics of these machines.</DIV>
<DIV> </DIV>
<DIV>These are made by Otari and used the thermal transfer. You'll see
that there is a vertical bin loop for the master. It's transfered onto a
pancake of 1/2" tape:</DIV>

<DIV>Here are the Sony machines....horizontal instead of vertical with the loop
bin on the right. These were magnetic instead of thermal:</DIV>

<DIV>And the Otari recorder that produced the mirror masters:</DIV>

<DIV> </DIV>
<DIV>And then the pancakes were loaded onto these machines which took empty
cassette shells, and automatically loaded each segment from the pancake into the
shell:</DIV>

<DIV> </DIV>
<DIV>As you can see, the loaders were as much (or more!) pneumatics as they were
electronics! Now of course, this too is all ancient history. I took
these pics at a liquidation sale of a large duplicating facility.</DIV>

<DIV>Tnx fer info, very interesting. I guess the tape onto which the
mirror image was recorded was not a standard tape? Was it made just for this
purpose??</DIV>
