We (and a number of other Apollo sites) are rapidly finding that using
magnetic tape as a backup medium is becoming impractical.  We are
primarily Electronic CAD, and presently have about 4.8 Gb of disk
storage, with lots of projected growth.

Has anyone had experience using a high density optical (WORM type) drive
on an Apollo system?  I would prefer a Multibus interface but will look
at an AT-Bus system.

Key features needed are high density (i.e.  > than the 120 MB we can get
on a tape), stability of the media for archival purposes, and cost/unit
of the optical media itself (must be low enough for use as a backup and
frequent archival media).  Drive cost is not as big of a concern.

As they say, "Thanks in advance"
