CD-ROM blanks will be slow to write, but are cheap (about $20 each) and
will hold about 700K.  They also have the advantage of being readable on
a large number of machines, provided you put things into a readily accessible
format.  You could also maintain an index CD.  Write times are slow compared
to a hard drive, but should be better than the tape.  Backup should be good
for 10 years, I think.  I would guess that price per gigabyte per year of
storage would be competitive with tapes.  The CD-ROM writable drives can
be had for as little as $2000.
