Density is a term used to describe the type and amount of storage area on a floppy disk. A disk is covered with particles of magnetic 'dust' that can store pieces of data. The larger the particles, the fewer the disk can hold and therefore the less information it can store. On a high-density disk, the particles are smaller; the disk can store more information because more particles can be packed in more densely. High density is not the same as "double density," which is an earlier technology still currently used that packs only about half as much data onto a floppy disk.
