These first floppy disks were a rather large 8 inches in diameter, but had a capacity of just 80 kilobytes. They were actually floppy, like the 5.25-inch disks that readers may be more familiar with, and in contrast to the rigid plastic-encased 3.5-inch ‘save icons.’ So, floppy disks are officially 54 years old, based on the patent application's grant and publication dates. However, work on this portable storage medium began in 1967 as part of IBM’s Project Minnow . This project proposed “a flexible Mylar disk coated with magnetic material that could be inserted through a slot into a disk drive mechanism and spun on a spindle” as a form of portable/removable media, instead of tape or punched cards.…
