This has been a long time coming. In spring of 2005, the company almost had to shut down, but was bought out at the last minute. However, it was obviously only a brief reprieve. Quantegy has been the only company still manufacturing reel-to-reel analog tape for at least a few years. However, ATR Magnetics has promised to pick up the ball, although they have not officially released any tape products as yet.
Still, you might want to stock up on Quantegy tapes, just to be safe!
