I pretty sure they're using StorageTek tape silos, these are 12
sided silos about 11' across holding around 5000 500 Meg tapes (I
have a 3-4 dozen upstairs), so the Arms move in a circle. The tapes
have laser read barcodes, so the arms can find and load a tape in
something like 2 sec.
Because they are 12 sided, you can butt them up against each other
like a honeycomb, and they can pass tapes to each other, it's
really cool, there is a string of them almost a 100 yards long
upstairs.
Don't you live in Chicago? You can stop by my office sometime and
see them.....
