One interesting story about the 5 1/4-inch floppy disk was the way the disk size was decided. The disks also had a 30 ms access time, and lubricated coating allowing the heads to remain in contact with the surface when rotation speed changes. Since that first disk drive, technological advances have been made at an astonishing rate, with data capacity increasing and size and price decreasing exponentially, year on year.
