Answer:
The Floppy Disk
In 1971, IBM introduced the first "memory disk” or the "floppy disk," as it is known today. The first floppy was an 8-inch flexible plastic disk coated with magnetic iron oxide. Computer data was written to and read from the disk's surface.
The nickname "floppy" came from the disk's flexibility. The floppy disk was considered a revolutionary device throughout the history of computers for its portability, which provided a new and easy means of transporting data from computer to computer.
The "floppy" was invented by IBM engineers led by Alan Shugart. The original disks were designed for loading microcodes into the controller of the Merlin (IBM 3330) disk pack file (a 100 MB storage device). So, in effect, the first floppies were used to fill another type of data storage device.
