DRM-7000 Operating Instructions
benzine, thinner, insecticide or other strong chemicals as these may dissolve or discolor the
cabinet surface. Some commercially produced chemical polishing clothes may be acceptable
but read all instructions and warnings first.
2.5 Managing Offline Media
The DRM-7000 provides the following features to manage of offline media.
• Removable Disc Magazines
Disc magazines may be removed from the Changer without removing the discs inside
thus making it possible to make more effective us of the space within the Changer.
Remove and store the magazines containing infrequently used discs.
• Unique Disc Magazine IDs for the DRM-7000
All disc magazines are assigned unique ID codes. The Changer reads this code as the
magazine is inserted into a bay. Each disc is accessible as soon as the magazine is
inserted into a bay. As long as the discs within the magazine match the database
information for that magazine ID. If a magazine is inserted into another Changer, the
new Changer recognizes the magazine if both Changers share the same database.
• Easy Disc Magazine Tracking and Controlling
Once a magazine has been assigned an ID, removing or inserting new discs into that
magazine disrupts the correspondence to the database. To avoid this problem,
purchase the 50-disc magazines with the locking mechanism. The locking magazine
prevents discs from being removed from a magazine while it is outside of the Changer.
Also use hyper magazines which track and record removal and insertion of new discs.
• Storage of Changer IDs
When a disc magazine has been inserted into a Changer not controlled by the
database management software or into a Changer belonging to another system, it is
possible for discs within that magazine to be rewritten or to be replaced with other discs
within that Changer. Locking magazines do not prevent rewrites or disc exchanges
when inserted into the Changer.
To protect the data, disc magazines are designed to record the IDs of the Changers in
which the magazines are used. As long as the list of Changer IDs is maintained within
the database, it is possible for the database management software to check the
magazine ID and the Changer ID list to determine whether that magazine has to be
reinstalled.
However, although the DRM-7000 Changer supports offline media, the actual media
management may differ because of the selected database software and the Changer
control software. Establish a set of management controls to handle the offline media.
To use non-locking magazines, the management controls must be very strict as these
magazines are usually unsuited for offline media management.
