Question: |
How does DiscJuggler know which disc is the source (or master) disc? |
|
Answer: |
If the "Copy CDs and DVDs from the same burner" task has been
chosen, DiscJuggler will check each disc that is loaded by the autoloader.
If a non-blank disc is detected, then an image of that disc is created
on the hard disk and used for duplication of all subsequent blank discs
until another non-blank disc is encountered. Alternatively, DiscJuggler
can use a reading drive that is external to an autoloader as
the source by selecting the "Copy CDs and DVDs on-the-fly" task. |
|
Question: |
What happens if a defective disc is detected during unattended operation? |
|
Answer: |
The disc is removed from the recorder and placed in the reject bin of
the autoloader. |
|
Question: |
Can DiscJuggler control multiple autoloaders simultaneously? |
|
Answer: |
Yes, however, the user must be careful to establish
a correlation between the robotic control and the associated drives of
each autoloader unit. Simply create multiple tasks and in each task select
a different autoloader. You must be careful to not create a situation
that is causing head contention on your hard disk. You can avoid hard
disk head contention by not running more than a two tasks on the same
fast hard disk (seek time less than 10ms) and adding additional hard disks
to your configuration if you will be running several independent tasks. |

Question: |
What type of quality assurance (QA) support exists for these production devices in DiscJuggler? |
|
Answer: |
Several. First, DiscJuggler can verify each disc against the source image after it has been duplicated and reject the few discs that are defective. This procedure, while providing an extremely high degree of assured reliability will nearly double the time needed for duplication tasks. Although, this reliability might be consistently required for some types of duplication tasks, less stringent procedures are available that will allow you to strike a balance between quality assurance and duplication productivity. These options provide for verifying only the first duplicated disc or one disc every x (where the operator can set x) discs.
An additional QA feature of DiscJuggler is the complete logging of each
disc that is duplicated in a text file. This file can log the operator's
name and other task-related data as well as a complete record of the duplication
process. DiscJuggler's "Test" feature also provides a valuable insight
into the reliability of a particular duplication task before it is begun
on a stack of discs so that all settings can be optimized for the maximum
probability of success. |

Question: |
What happens if a disc is improperly loaded into the writing drive or dropped? |
|
Answer: |
DiscJuggler is designed to provide a reliable, unattended solution,
and depending on the device in use, DiscJuggler will try to apply all the available
recovery procedures. In the unlikely event that a disc cannot
properly loaded or unloaded, the application will stop immediately all processes and advise the operator of the problem. This is necessary
in order to avoid damaging internal autoloader components. |
|
Question: |
What percent of blank discs are normally detected as being defective? |
|
Answer: |
It greatly depends on the quality of the media used, but under normal
circumstances, if the writing speed never exceeds that for which the media
was certified this percentage should not be higher than 1%. |
|
Question: |
Do I need a special version of DiscJuggler to operate an autoloader? |
|
Answer: |
Yes, these are specialized devices that require special software development
on the part of Padus and extensive testing by the device's manufacturer. As
a result, the software is usually sold with the device as part of a complete
solution. |
