Was not Irish factory seconds of Scotch? And then there was the company that recycled Ampex which I believe they said had been used by the government?
Did not IBM in the early years use tape from 3M?
I don't recall that the Magnetic Recording Handbook has much history in it...my copy is at home.
Does anyone know of a published history which would trace all of the various manfacturers and brands?
