DVD-RAM
Drives
Maxoptix DVD jukeboxes are available in a range of sizes to
suit most environments with both 5.25GB and 9.4GB drives as
options. With
these Maxoptix jukeboxes, you have total flexibility with 2
drive type DVD-RAM libraries: The DVD520 and DVD540 use 5.2GB
double-sided (2.6GB per side) DVD-RAM cartridges. This gives
the 20-cartridge DVD520 a capacity of 104GB and the 40-cartridge
DVD540 a capacity of 208GB.
| The
jukeboxes feature a flipping mechanism to take advantage
of the storage capacity on both sides of the discs, and
are available with one or two drives. The DVD620, DVD640,
DVD6436, DVD6911 and DVD61840 use new 9.4GB drives. Enabling
capacities in the units of 188GB to 17.296TB depending on
the drive/slot configuration. The compact libraries fit
under a desk and are compatible with Apple Power Mac, Windows
NT4.0/2000, Solaris and UNIX environments, with management
software available from independent software vendors. Connectivity
is via SCSI interface. |

Media
The jukeboxes use standard cartridges that are approved and
recommended by DVD Forum. Media cost is also a concern with
libraries. Maxoptix jukeboxes use standard double-sided cartridges,
which cost about half as much as the media used by competitive
units. This can result in cost savings of several hundred dollars
per jukebox.
To isolate DVD-RAM for a moment and ignore alternatives such
as recordable CD media, the first step is to understand the
variations between DVD standards and clarify the media hype
over incompatibilities.
