Detailed explanation-1: -The first floppy disk was introduced in 1971. It was an 8-inch flexible magnetic disk in a square case.

Detailed explanation-2: -Initially the disk was bare, but dirt became a serious problem so they enclosed it in a plastic envelope lined with fabric that would remove dust particles. The Floppy Disk Patent #3, 668, 658 was issued on June 6, 1972, with named inventors Ralph Flores and Herbert E. Thompson.

Detailed explanation-3: -In 1971, IBM introduced the first “memory disk, ” better known today as the “floppy disk.” It 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 first Shugart floppy held 100 KBs of data.

Detailed explanation-4: -The floppy got its start at IBM’s data storage skunkworks in San Jose, California. In 1967, a small team of engineers under the leadership of David L. Noble started working on developing a reliable and inexpensive system for loading instructions and installing software updates into mainframe computers.

Detailed explanation-5: -The floppy disk drive (FDD) was invented at IBM by Alan Shugart in 1967. The first floppy drives used an 8-inch disk (later called a “diskette” as it got smaller), which evolved into the 5.25-inch disk that was used on the first IBM Personal Computer in August 1981.
