Orbit II Disc-to-Disc Copier Reference Manual – Revision J
28
6.4 Copy and Compare?:
This Orbit II operating mode compares the content of the master disc to each disc you copy, before the
disc is placed in the Accept Basket. Following every copy operation with a compare operation gives you
the highest confidence in the discs you copy and distribute. The Compare operation works with both data
and audio masters. Data masters will be verified, bit for bit, against the master. Audio masters, or masters
that contain audio (such as CD Extra), will go through a “Read Check”. This read check will verify that the
duplicated disc can be read and has the same structure as the master. Because there is audio on the disc,
it cannot be “bit for bit” verified. We suggest you use Orbit II’s
Copy and Compare?
Mode:
•
When you want the highest level of confidence in the copies you produce.
•
Your Orbit II is new, has been moved to a new location, or has been returned from
servicing.
•
You are using a master from a new source.
•
You are qualifying a new source of blank discs.
Compare operations are performed at approximately the same rate as copy operations. Using Orbit II’s
Copy and Compare?
Operation will reduce the number of discs you can produce in a given amount of
time by approximately 50%.

back to the “10s” digit by pressing the
No
until the “1s” digit changes from “9” to “0”.)
