Were Floppy Disks Floppy?

The 5.25-inch disks were dubbed "floppy" because the diskette packaging was a very flexible plastic envelope, unlike the rigid case used to hold today's 3.5-inch diskettes.

Are floppy disks actually floppy?

The floppy disk drive stores data on a thin flexible plastic disk coated on one or both sides with a magnetic film. Although the disk itself is floppy, and early ones were enclosed in flimsy cardboard covers, most disks are nowadays enclosed in a stiff plastic cover.

When were floppy disks discontinued?

The 3.5-inch floppy disk format was the last mass-produced format, replacing 5.25-inch floppies by the mid-1990s. It was more durable than previous floppy formats since the packaging was rigid plastic with a sliding metal shutter. It was eventually made obsolete by CDs and flash drives.
