What Is the Capacity of a Floppy Disk?

The floppy disk was first developed to replace the use of punched cards, which during the 1960s was the only way to get information and software onto a computer. David L. Noble was assigned the task of replacing them and developed a flexible disk, coated in magnetic material that could hold the data of 3,000 punch cards. These floppy disks got dirty easily, so Herb Thompson and Ralph Flores developed a special envelope that would ward off dust and keep them clean.
