<para>disk: A circular disc, covered with magnetic or
similarly manipulable material, spun by a motor under a
head. Data is stored on the disk by changing the pattern
of magnetism on the disc, which can be later read. Hard
disks, CDROMs, Magneto-optical,and Zip/Jaz removables are
examples of disks.</para>
<para>disk: Hard disks, CDROMs, magneto-optical devices and
Zip/Jazz removable media are example of storage devices
commonly used today. The basic principle of the way these
work is that one or more spinning disks spin by a motor,
while a head, moving on a radial path close to the disks,
reads from or writes data to the disk. Writing is done by
modifying some physical properties of the disk (magnetic
flow, reflectivity, etc.) while reading is done by
<quote>detecting</quote> changes to the same physical
properties of the disk.</para>
