The Defaults panel contains important settings to control the way that DiscJuggler routinely burns discs unless an alternative is requested in the course of a specific recording task. By checking the appropriate boxes, you can request that DiscJuggler to perform combinations of actions, different methods, read and write CD sub-codes, and a wide range of additional options.

Actions

• Test

• Write

• Verify

Use these three controls to define the default way the "Action" panel will be initialized during a creation of a new task. Any combination is valid except for Test and Verify.

• Cache

By selecting "Cache" you effectively disable burn-on-the-fly and you force DiscJuggler to save the source disc to a temporary image on your local hard-disk first.

• Copies

This control will define the number of copies automatically selected by DiscJuggler in the "Action & Method" panel, each time a new task is created. Directly edit the control field or use the spin-buttons to enter a positive number or "Auto" in which case the number of drives selected will determine the number and DiscJuggler will ask for more blank discs at the end of every cycle.

Methods

• TAO

Selecting this option will force DiscJuggler to write discs in Track-At-Once (TAO). TAO forces a 2 seconds gap between tracks and adds a few additional unreadable blocks at the beginning and at the end of each track. DiscJuggler uses by default Session-At-Once (SAO) when supported by your drive. Use TAO recording method only if for any reason your writing drive is not working in SAO or Disc-At-Once (DAO) writing.

• RAW

RAW write will disable the automatic hardware regeneration of error correction codes and reproduce the source data "as is" using, whenever possible (not all recorders allow this option), the RAW recording method. When this option is selected, DiscJuggler will read and write blocks and associated sub-codes transparently without interfering with their content.

Checking this box can be useful if intentional discrepancies between the error detection encoding and user data are present in the source. This option should be used with extreme caution as DiscJuggler cannot detect legitimate read errors when operating in this mode.

CD sub-codes

• Scan gaps/indexes

This option will force DiscJuggler to accurately scan the source disc to reproduce the exact index structure and to search for tracks. This option is only related to Audio CDs. Please be aware that identifying the exact source disc index layout (including gaps between songs) can take a considerable amount of time. Select this option to make sure that the exact index structure and track layout of Audio CDs are replicated.

• Read ISRC/UPC

This option will force DiscJuggler to accurately scan the source disc to search for tracks and disc unique identifiers such as the ISRC (International Standard Recording Code) and UPC (Universal Product Code) codes. This option is only related to Audio CDs. Please be aware that the ISRC and UPC codes are rarely used in commercial Audio CDs and scanning for them can take a considerable amount of time.

• CD-TEXT

Checking this option will instruct DiscJuggler to read/write information such as the name of the album, the artist, and the track titles of Audio CDs.

• PQ

When this option is selected DiscJuggler will not regenerate/correct PQ sub-code data, but will instead use whatever CD data was provided by the source drive. This is only possible if the writing drive is capable of recording in RAW mode. This option should be used with extreme caution since not all the reading drives can return valid PQ data, in which case the resulting CD will be unreadable.

• R-W (CD+G)

Select this option if you want to duplicate Karaoke CDs or you want to create Karaoke compilations. Select also this option, combined with "RAW" to write R-W data returned by the source drive unchanged.

• R-W de-interleaved

Reads R-W sub-codes in de-interleaved mode. Some older drives can only read and write R-W sub-codes in de-interleaved mode.

Buffer under-run prevention

Most drives feature buffer under-run prevention technology to limit the possibility of the drive buffer losing data and preventing the writing process from succeeding. This technology pauses the writing process until the buffer has the necessary data to complete the process and begin again where the process was paused. This procedure, while saving the write process, will increase the total writing time. Common names for the technology include BURN-Proof™, JustLink™, Power-Burn™, SafeBurn™, and Seamless Link to name a few. DiscJuggler can use this technology in the following ways.

• Disable
  
  This option will force DiscJuggler to not use any buffer under-run prevention technology that writing drives feature.
   

• Enable
  
  This option will for DiscJuggler to use any buffer under-run prevention technology that writing drives feature.
   

• Enable with only single drive tasks
  
  This option will make sure DiscJuggler only uses buffer under-run prevention technology in tasks where only one writing drive is being used. Tasks involving more than one writing drive will not use any buffer under-run prevention technology.

Miscellaneous

• Enable network CD/DVD burning
  
  By default, certain DiscJuggler editions will automatically have networking support enabled. This allows DiscJuggler to know of available servers using the DiscJuggler.NET architecture by scanning for servers while DiscJuggler loads. This can be disabled to shorten the time DiscJuggler takes to load and make servers unavailable as destination devices in certain tasks.
   

• Add post-gap to 3rd party images
  
  Checking this option adds a two second gap to the end of a disc image that was not been created by DiscJuggler. If you create discs without adding a two second post-gap, some drives can accidentally step on the lead-out area while trying to read files recorded at the end of the disc, resulting in read errors.
   

• Maximum DVD compatibility (minimum 30 mm radius)
  
  Some DVD writing drives require that at least 30 millimeters of data is written to a blank disc, while others make it optional. While it is recommended that you use this feature for increase compatibility with all reading drives, you can disable this feature if you are certain that the resulting disc will be compatible. With drives that do not provide the option, DiscJuggler will write null data until 30 millimeters is reached, which can increase the time it takes to finalize DVD discs.
   

• Set DVD-ROM BookType
  
  This option will use bitsetting technology of supported writing drives to change the BookType of DVD+R, DVD+R DL, and DVD+RW media to DVD-ROM for higher compatibility in DVD players.
   

• Ignore read errors
  
  Some CDs will intentionally incorporate illegal sectors that will cause a read to fail with an error. If this box is checked, DiscJuggler will simply ignore these errors and supply the destination drive with dummy (empty) blocks instead. Please do not check this box unless you know that the disc you are duplicating contains bad sectors.
   

• Truncate CD/DVD
  
  Check this box if you want to truncate (cut off the end) of your source disc or image so that it fits on a standard size blank disc. Truncation may make sense for an Audio CD but it will most likely render a Data CD or DVD unusable. DiscJuggler will give you the choice of truncating or terminating on a task-by-task basis if you have checked the box for this in the confirmation dialog.
   

• Overburn CD/DVD
  
  You can attempt to "overburn" a disc that exceeds the maximum size of a standard disc by checking this box. When you select this option DiscJuggler will simply ignore the maximum available space on the target disc and will let you start the recording process anyway. However, there is no guarantee that you will be successful or how much space, if any, is available beyond the standard maximum size for the disc brand that you are using. DiscJuggler will give you the choice of overburning or terminating on a task-by-task basis if you have checked the box for this in the confirmation dialog.
   

• RAW 30 sec. CD leadout
  
  The CD-R/RW standard (the so-called "Orange Book") mandates that the first session on a CD must have a lead-in area of 1 minute and a lead-out area of 1 minute and 30 seconds while second or higher sessions must have a lead-in area of 1 minute and a lead-out area of only 30 seconds. When this option is selected along with "RAW read/write" DiscJuggler will generate a first session lead-out area of only 30 seconds. While still perfectly compatible with most reading drives, this shortened lead-out area will free up to ~9 MB of available disc space. On credit-card size CDs this can translate on a 15% or more increase in available free space.
   

• Read speed
  
  Use this control to adjust the reading speed at which data and audio are extracted. Slowing the reading speed can be a valuable means of improving the quality of Digital Audio Extraction (DAE) on some readers. Normally, some experimentation is needed to determine the optimum setting. Please be careful to set the read speed at or above the write speed when duplicating directly to a recorder to avoid buffer under-run problems.
   

• Write speed
  
  Use this control to define the default way the "Method" panel will be initialized during a creation of a new task. Depending on the writing drives in use, not all the speeds may be available: in this case DiscJuggler will automatically choose a compatible speed.
   

• Image size
  
  These controls set the maximum disc size. This size should match the size of the blank media used or should be larger for the ability to "overburn" discs. Directly edit the control field or use the spin-buttons to enter a positive number based on the approximate block size of discs.
   

• DAE jitter correction
