A disk with usable recording surfaces on each side is known as A. Hard disk B. Single-sided disk C. Double-sided disk D. High capacity E. None of the above
In computer science, a double-sided disk is a disk of which both sides are used to store data. Early floppy disks only used one surface for recording. The term single-sided disk was not common until the introduction of the double-sided disk, which offered double the capacity in the same physical size.
