Copying CDs/DVDs
12.1 Copying methods
Nero Express can be used for copying discs. There are two methods for this:
On-the-fly
Copy Over Image
Each method has advantages and disadvantages which will depend on your requirements.
12.1.1 On-the-fly
When using the on-the-fly method, insert the original disc into a drive and a recordable disc
into the drive. The original disc in the drive is copied immediately without any time delay to
the blank disc in the recorder. The on-the-fly method all
and does not require any additional space on the disc.
In order to be able to use the on-the-fly method, you will need at least two drives: one for
reading the disc and a
drive and disc burner:
The disc burner must feature buffer underrun protection, or the drive must be capable of
delivering the data sufficiently quickly. The read speed should be at least twice as fast as
the write speed.
The read drive must be capable of delivering information on the number and type of ses-
sions, otherwise Nero Express may not be able to produce an exact copy.
If you want to copy Audio CDs, we recommend the copy image method because the quality
of the read audio files can suffer depending on the drive.
12.1.2
Copy image
With the copy over image method, an image of the original disc is saved to a file first. The
image file is then burned to a blank disc. Copying using copy over image take
often produces better results.
You must have sufficient storage space to use the copy over image method.
