[QuadList] Little more fun

George:

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.

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:

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

And the Otari recorder that produced the mirror masters:

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:

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.

  Bill,

  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??
