Comparing Discs
Comparing Discs allows a copy to be compared against a master image, to make sure
there are no detectable differences. This feature is not available for Audio or Video
tracks, because Audio/Video tracks do not have ECC (error correction codes) to
guarantee data integrity.Only data tracks have this.
Follow the Copying Discs section above, but instead of inserting blank media, insert
the copied discs.
Batch Mode
Batch mode is a method of copying more than one master CD without starting each
job individually.
This works by the system recognising new master discs the time they are loaded in to
the recorders from input hopper.
Each master disc should be placed on the input stack together with the blanks in such a
manner that the master would be loaded first, followed bythe blanks.
Each master and the required number of blanks should be placed in the input hopper
until all masters and blanks are on, or the input hopper is full.
Ensure that the first master is the first disc to be loaded.
A batch job will terminate if the input hopper is empty and all discs have been
recorded or if the first master being read has errors. A read error on a master midway
through will result in the following blank discs being rejected until a new master is
detected by the system.
