Not that it matters at this point, but 3M's magnetic division was acquired by Quantegy shortly after Quantegy acquired Ampex magnetic division (1996) and they had a good run for another ten years perfecting 3M and Ampex formulations. In addition we had BASF resurrected as EMTEC and finally RMGI. And now ATR Magnetic.
Tape just doesn't want to die and I'm sure it's not going away quietly anytime soon. That being said, as far as hardware is concerned we're looking at refurbs like from ATR and smaller shops restoring machines on a smaller scale, or just people like you and me doing it ourselves for the foreseeable future. And that's just peachy because the parts are out there and we can keep them running. My machines are good as new... maybe even better.
