Has anyone mentioned magneto-optical storage media? Supposedly it has
a very long life, believed to last into many decades to over a
century. It is impervious to magnetic fields.
Magneto-optical storage is a strong contender with some drawbacks. While
storage on the medium is expected to be very long and very stable, there
are internal moving parts. In practical terms, the limitation is cost and
potential obsolescence. They are closely related to one another and to the
lack of technology development in recent years. They still operate near the
price per MB of several years ago when that point was reasonably
competitive and the capacity was high. Today, the capacity per drive is
less attractive and other media are far less costly. The combination means
that there are few new buyers, reducing the incentive to improve the
technology or to use that improvement to lower cost.
