Most electronic data is stored on magnetic hard drives that spin at many thousands of revolutions per minute. To keep pace with ever-growing storage demand, however, achieving greater storage capacities by simply increasing the size of disks is infeasible. The required spinning speed would put immense physical strain on the components, particularly on the writing 'head'—a small needle-like object used to write data at particular points on the disk.
