Drivetec Floppy Drives

Whoa, hold the phone here. Okay, I'm trying to solve a twenty-year- old mystery. So, you say the media for these drives were made by Kodak? Did they, per chance, have *triangular* notches in place of the traditional rectangular ones? I'm asking, because in 1985 or '86 I was at an electronics scrap yard in L.A., and saw a *very* large heap of these kinda strange looking floppy drives. I don't remember too much about them, but I just remember they looked *weird*. The media was made by Kodak (something I had never seen before), and the notch on the edge of the floppy disk was *triangular*. I figured it was some special media for bio-medical equipment, or for some bizarre photographic process, or something. Anyways, I never saw drives (or floppies) like that ever again, and always wondered about it. They looked brand-new, and the whole incident sticks out in my mind because I remember the owner was mad as hell-- apparently he spent a small fortune on these things, but nobody wanted them because they weren't 'standard'.
