The Burn tab on the Burn Compilation window provides options for the burn process. Which options are enabled, depends on the chosen compilation.
The following check boxes are available in the Action area:
Check box
Determine maximum speed
Checks how fast the compiled data can be accessed and reduces the selected writing speed if necessary. This prevents a buffer underrun.
Recorders with a feature to prevent buffer underruns do not require a speed test.
Not available when saving with Nero Image Recorder.
Check box
Simulation
Simulates burning. In the process the simulation performs all steps that are also carried out during burning with the exception of setting the laser beam. A test determines whether there is a constant flow of data. 
Check box
Write
Enables the Burn button.
Check box
Finalize Disc
Closes the disc so that you cannot write to this disc anymore. Depending on the disc format, finalizing may be necessary. 
Nero Burning ROM automatically checks the box for the relevant disc formats.
The following configuration options are available in the Writing area:

 

Drop-down menu
Write speed
Selects the write speed at which the disc is burned.
Drop-down menu
Write method
Selects the method used to burn the disc. The following methods are available. 
Track-at-once: Burns each audio file (track) separately onto the disc, i.e. the laser is turned off and turned on again after each audio file.
Disc/Session-at-once: Burns each session of a multisession disc separately onto the disc. 
Disc-at-once/96: Burns the entire disc in one go without having to turn off the laser between individual audio files. 
Input field
Number of copies
Defines the number of discs that are to be burned. The default is set to one disc.
Check box
Buffer underrun protection
Provides buffer underrun protection.
This check box is only available if the selected burner supports a method which offers buffer underrun protection. 
Check box
Using several recorders
When you click the Burn button, a window is opened in which you can select the desired recorders. The burn process is then carried out simultaneously on the selected recorders.

 

 
 
The speed test and simulation are not required for recorders that have a function for protecting against buffer underruns. Current recorders mostly have such a feature.
 

 

 
 
Audio CDs should always be burned using the disc-at-once method. This entry is selected by default.
 
Disc-At-Once
Disc-At-Once refers to a method in which the laser in your recorder burns straight through in one session without turning off and on between each track. This method is best when recording Audio CDs you would like to play in your home or car stereo.
