3. Iomega Zip® and Jaz® disks*
Images can be copied from the internal hard disk or RAID onto removable Zip® or
Jaz® disks for longer- t e r m storage. All images are digitally signed before being
t r a n s f e r red to disk. These images can be played back on a Windows™ PC with a Zip
or Jaz drive connected and DM Playback software installed.
Note: PC playback is available to download from our web site, the unit itself, and
is included with the unit on Disk.

4. External tape storage
Images recorded to the internal disk can be automatically archived to Hewlett
Packard DDS. This allows a ‘tape-a-day’ recording solution, similar to that of a
multiplexer and VCR. The disk size does not have to be large when using tapes
to archive images, although the disk size determines what is instantly accessible
from the Digital Sprite 2.
To play back images recorded to tape you will need to use a second tape unit
connected to a Windows™ PC. PC playback* software is required to play back
the images on the PC.
N o t e : Due to the mechanical wear of tape drives and tapes we have found that they
a re not generally as reliable as using disk and RAID storage alone, there f o re we
would not recommend using tape storage unless there is no other option available.
The table below shows the number of hours a tape will last for when used at
different record rates (at S-VHS images quality, 18KB)
