   I don't know about the interfacing problems, but I thought the
last time I looked at the price for MO and WORM drives they looked
very competive as far as Mb/$, when compared against a regular
magnetic disk (especially if the magnetic disk is purchased from
SGI).  Especially since you can use multiple disks in the
MO and WORM drives.  Also, they ARE random access.  It sounds
rather ridiculous to me to call a DAT a random access device.
   WORM drives look very promising if you need fast access to large
permanent archives.
