I'm not so sure about the different oxide concept; I was recently told by a person familiar with the industry that non-high-density 3.5" diskettes are merely those diskettes which failed the manufaturer's tolerance tests. They are then marketed as 720K. Believe it or not. Don Meyer University of Illinois, at Urbana-Champaign meyer@s.cs.uiuc.edu
