Meridian Data Systems and Reference Technology sell turnkey sys-
tems (MS-DOS based) which will produce nine track tapes. CD-ROM
is system independent so if you can get your tar tapes read on
the nine track drive you can make disks.

ANSI labeled tapes in ISO 9660 format should be accepted by ever-
ybody but PDO (Phillips) who require some kind of additional
header as well as the CD-ROM image. Disktronix would even make a
tape from an ANSI file tape if proper documentation was provided
(I don't know about tar tapes). The easiest way to made a disk is
to get a Yamaha WORM drive that makes CD-ROM compatible media and
interface it to your UNIX machine.

There will never be a total list because probably a majority of
disks being made are limited distribution. A good way to receive
information on all upcoming CD-ROM products is to join SIGCAT by
contacting E. J. "Jerry" McFaul at the U.S. Geological Survey,
Reston, VA.

Someone already answered this, but note that this is one of the
confusions of CD-ROM. Some disks have been produced that can be
played on both MacIntosh and IBM-PC computers, but as always a
Mac executable is gibberish on a PC and vice versa. To get a PC
software module to work under *NIX a compatibility window (or
equivalent) must be used.

For the drives we have, my preference is Hitachi, then Sony, and
lastly Phillips. Since you have said you want SCSI, I recommend
that you get a driver that caches at least one full track of the
CD-ROM.
>4a- Are there any CD-ROM jukeboxes ? (We need a SCSI interface

I have talked to several WORM jukebox manufacturers and they say
that the CD-ROM drives that use a disk carrier can be installed
in their equipment. However, since the profile of the CD-ROM car-
rier and the WORM cartridges are different, some modification of
the existing hardware is required.
