I just recieved some of these tapes today that i purchased on ebay (Killer Tapes) and i noticed that on a couple of the tapes it say's "FERMO" in gold letters and on the rest it say's the normal MA-XG in gold letters,does anyone know what "FERMO" means and why some say FERMO on them and some just say MA-XG?Just curious,Thanks..Keith H.
