The overburn process simulation is run in the Nero DiscSpeed – Overburning Test window.   
The results are displayed in the same window, in the Write position and Disc information areas, as well as in the display area at the bottom of the window.
You can define preferences for the test in the top section of the window. The following setting options are available:
Menu
Write speed
Defines the speed at which burning of the disc is simulated.
We recommend that you choose a speed of 16x or less when burning an audio CD.
Input field
Test capacity
Shows the disc capacity in MSF (minutes/seconds/frames).

 

Check box
Simulate
If this check box is selected, Nero DiscSpeed simulates the burn process rather than writing data to the recordable disc.
This check box is selected by default.
Check box
RAW mode
If this box is checked, the burn process will be simulated in RAW mode.
The following information on the burn process simulation in progress is displayed in the Write position area:

 

Position
Continuously indicates the current position of the read head on the disc.
Relative
Always indicates the percentage of the disc that has already been written.
Shows the progress of the simulated burn process:
Green – Data written within the disc’s normal capacity.
Yellow – Data written past the disc’s normal capacity.
Dark green – Buffer status.
Blue – Standard, official disc capacity.
Red – Current position of the read head on the disc.
The following information on the disc that is inserted in the drive is displayed in the Disc information area and in the display area

 

Capacity
Shows the disc capacity both in MSF (minutes/seconds/frames) and in MB.
Maximum specifies the maximum volume of data that can be written to the disc with the help of additional capacity achieved through overburning.
Extra – Shows the difference between normal capacity and maximum capacity.
Manufacturer
Shows the manufacturer’s name.
Dye type
Shows the dye type used.
Disc type
Shows the disc type of the disc in the drive.
Dye type
There are different materials of different colors that are used to produce storage media. The laser-sensitive and data-carrying dye layer can e.g. be made of phthalocyanine or formazan.
Disc type
Disc type refers to different optical storage media with different specifications. The best known are CD’s and DVD’s that can be written to once or multiple times, and which are manufactured with different storage capacities.
