8" Floppy Disks

Have you seen 8 inch Floppy disks?? Well whether you have heard about them or not they were the original "memory sticks." A floppy disk is a thin, flexible (floppy) magnetic storage in a square or rectangular plastic case. A floppy disk is a data storage device that was introduced by IBM in 1971. David L. Noble and his team developed a read only, 8-inch-diameter flexible disk, which could hold 80 kilobytes. IBM first started developing them in 1967 and it was developing for a more simple and inexpensive system for loading microcode. Microcode is coded instructions that are stored permanently in read-only memory. It cost customers around $5. Floppy disks were read and written by a floppy disk drive. But in 1976 the 5 1/4 Floppy was introduced and the 8 inch Floppy disk was quickly replaced. The 5 1/4 floppy could hold 110 kilobytes and were cheaper to buy.
