The detected writer is displayed under this pop-up menu. You can select the speed
here too.
WARNING: Select the Writing Speed with Care
Normally, you should select Auto, which chooses the maximum writing
speed possible. However, if you increase this value but your system is not
able to send the data fast enough, the likelihood of buffer underruns in-
creases.
Writing Mode
This option determines how the laser writes the CD or DVD. For CDs, there are
three modes available: DAO, TAO, and RAW. In DAO (disk at once) mode, the
laser is not deactivated while the disk is written. This mode is recommended for
the creation of audio CDs. In the TAO mode (track at once), a separate write process
is used for each individual track. The RAW mode is not used very often, because
the writer does not perform any data corrections.
For DVDs, there are also three modes available: DAO, incremental, and overwrite.
For DVDs, DAO mode does not support multisession. If you want a multisession
DVD, select the incremental mode. The overwrite mode allows increasing the
ISO9660 file system from the first session on rewritable media using growisofs.
Usually, it is best to select Auto, because it allows K3b to use the most suitable
settings.
Simulate
This function can be used to check if your system supports the selected writing
speed. The writing is performed with the laser deactivated to test the system.
On the Fly
Burns the desired data without first creating an image file (do not use this feature
on low-performance machines). An image file—also known as an ISO image—is
a file containing the entire CD content that is subsequently written to the CD exactly
as it is.
Only Create Image
This option creates an image file. Set the path for this file under Temporary File
on the Image tab. The image file can be written to CD at a later time. To do this,
