The rise and fall of 3M’s floppy disk

Even with that said, those gray-hairs will frequently claim that of the many makers of floppies out there, 3M made the best ones. Given that, I was curious to figure out exactly why 3M became the most memorable brand in data storage during the formative days of computing, and why it abandoned the product.

I do not remember if I ever held any particular views on which brand of floppy disk (or diskettes, as we called them) was the best. We had a wide variety of brands, and I can’t recall any one of them being better than the other, but then, I’m sure people in professional settings had more experience with the little black squares and thus developed all kinds of feelings about them.
