Well, I'm unsure what's on those reels but they have huge hubs holes.

I remember some sort of hard drive you could see into, had a tall stack of disks about 18" in diameter. If I recall you could actually change the "cartridge" on those.

Never used the mylar tape, we still used paper on a CNC machine in the mid 70s.

That is why they changed so the chaff remained attached to the tape on one portion of it's perimiter. Consistent with the change to the "pop-top" can. The disposable tabs were becoming quite a problem, ecologically speaking. Also, the little chips or "punches" from the 80-column type IBM card were quite hazardous even after being thrown from a 20th-story window in a large quantity because they tended to fall as a mass.
