| The read/write head of a zip drive is about one tenth of that
of he floppy drive because of higher data density resulting in more compacted
data. As a result, the zip disk has 2118 tracks compared to the floppy drive's
low 135 tracks.
The disk space is furthermore increased by coating
with magnetic material. On the disk surface, magnetic particles are
applied, thus the disk surface is made harder to magnetize, so when
magnetization occurs, the area affected will be minimal. This will again
increase the disk space.
Lastly, zip disks uses zone recording, meaning
that more the same amount of information, the same amount of physical
space is used up. There are more sectors on the outer tracks compared to
the inner tracks. This working mechanism is similar to that of the
hard disk, thus maximizing use of physical space.
