SECURITY FEATURES

Information on the location of discs within the changer and

information to access data on discs are strictly monitored

and controlled from the changer control software and the

upper-level database management software.

Because of this, if any changes in the status of the discs

within the changer occur at a time when the changer is not

under the control of the host computer (or in a network

environment, under the control of a server), it becomes

impossible to control the changer and drives and to read

necessary files from discs.

Allowing discs stored within the changer to be removed

without any restrictions poses a security risk, not only in that

it would become impossible to access discs which have been

removed but also in that it might lead to the damage or loss

of discs.

Although the DRM-7000/DRM-3000 has been designed so

as to open the front and rear access doors from the control

panel (located at the top of the front of the unit) to remove

magazines or to insert or remove discs through the mailslots,

anyone who considers the security issues noted above will

be able to understood that it is necessary to place restrictions

on such operations.

This is why the control panel of the DRM-7000/DRM-3000

has been fitted with a key switch which may be locked to

disable operations of control keys. This switch cannot be

unlocked without the key provided with the DRM-7000/DRM-

3000, and if the system administrator will always keep this

key, it is impossible that ordinary users without key perform

unauthorized operations from the control panel.

It is also possible to restrict the range of operations which

are performed from the control panel. It means that a part of

system administrator’s privileges is controlled by the

command issued from the host computer and even if a

system administrator has the key, the host computer makes

it impossible to open the access doors, exchange discs, or

perform other unfavorable operations for itself.

OFFLINE MEDIA MANAGEMENT

The DRM-7000/DRM-3000 provides the following features

which makes it perfect for the management of offline media.

¶ Removable disc magazines

Disc magazines may be removed from the changer with

the discs left in the magazines. The use efficiency of the

space within the changer may much improve if the

infrequently used discs are collected in one magazine and

it is taken out from the changer into the offline storage.

¶ Unique disc magazine IDs

All disc magazines used in the DRM-7000/DRM-3000 are

assigned unique ID codes which makes it possible to

identify individual magazines simply by inserting them into

the magazine bays.

All of the discs within an inserted magazine become

available immediately no matter which magazine bay it is

inserted into as long as the discs installed in the magazine

have been registered in the database as corresponding to

the magazine ID in question, and the same holds true when

a magazine is inserted into a different changer as long as

the changer in which it is inserted is under the control of

the same database.

¶ Disc magazines designed for easy tracking and control

Removing, inserting or replacing discs in magazines after

they have been removed from a changer may destroy the

correspondence between discs and magazine IDs.

To solve this problem, Pioneer provides 50-disc magazine

which has a locking mechanism to prevent all attempt to

change the status of the magazine outside the changer

and hyper magazine which has a smart memory system

that records all user operations toward its lock/unlock

mechanism so as to make it easier to track and control

the use of offline media.

¶ Registration of changer ID

When a disc magazine has been inserted into a changer

not under the control of the database management

software or into a changer belonging to another system,

the discs within that magazine may be rewritten or may

be replaced with other discs within that changer. Even if

the magazine in question is a locked-type, these

discrepancies between the discs actually contained within

the magazine and the information on those discs stored in

the database may be arise.

In order to prevent such problems from occurring, disc

magazines are designed to record the ID of the changer in

which they are used, and as long as the database has a

list of the IDs of changers controlled under the given

database, it is possible for the database management

software to determine whether or not a inserted disc

magazine has to be reinstalled by checking the changer

ID that may be read with the magazine ID.

However although the DRM-7000/DRM-3000 changer and

disc magazines do provide the features needed for the

management of offline media, it should be noted that the

actual procedures and methods available for the management

of offline media may differ depending on the database

management software and changer control software being

used.

It should further be noted that it is necessary to establish

how to employ controls for the handling of offline media. In

fact if management controls are strict enough, it is even

possible to use normal-type disc magazines which would

ordinarily be unsuited for use in the management of offline

media, in the same way as one would use locked-type disc

magazines.
