<P>
A tape drive uses a tape, similar<A NAME="tex2html15" HREF="footnode.html#1070"><IMG ALIGN=BOTTOM ALT="gif" SRC="./foot_motif.gif"></A> to cassettes used for music. A tape is
serial in nature, which means that in order to get to any given
part of it, you first have to go through all the parts in between.
A disk can be accessed randomly, i.e., you can jump directly
to any place on the disk. The serial access of tapes makes them
slow.
<P>
On the other hand, tapes are relatively cheap to make,
since they do not need to be fast. They can also easily be made
quite long, and can therefore contain a large amount of data.
This makes tapes very suitable for things like archiving and
backups, which do not require large speeds, but benefit from
low costs and large storage capacities.
