The Read Option tab consists of several areas. In these areas it is possible to set options for reading an original disc.
The following configuration options are available in the Profile area:
Drop-down menu
Profile selection
Selects predefined copy settings or a user-defined setting.
In the case of predefined copy settings, Nero Burning ROM sets the configuration options automatically. You can select the configuration options yourself with a user-defined setting.
The following configuration options are available in the Database area for the CD disc type:
Check box
Ignore read errors
Ignores read errors on the original disc and continues the read process. 
If this check box is cleared, Nero Burning ROM may interrupt the burn process depending on the type of error.
Check box
Write defect sectors
Still passes on corrupt sectors (that have caused read errors) for burning.
If this check box is cleared, corrupt sectors are not passed on and remain blank.
Check box
Read sectors in raw mode
Reads PQ subchannel data.
Check box
Read all subchannel data
Reads all subchannel data during copying. Subchannel data is used to save additional information.
The burner has to be capable of reading all the subchannel data.
The following configuration options are available in the Audio Track area for the CD disc type:  
Check box
Ignore read errors
Ignores read errors on the original disc and continues the read process.
If this check box is cleared, Nero Burning ROM may interrupt the burn process depending on the type of error.
Check box
Read indexes of audio data
Reads the audio file indexes. This is particularly useful for copying an Audio CD as it makes sure that all index positions of the Audio CD are copied correctly. The disadvantage is that it increases the time it takes to analyze a disc before the copy process starts.
Check box
Read all subchannel data
Reads all subchannel data during copying. Subchannel data is used to save additional information, e.g. CD Text.
The burner has to be capable of reading all the subchannel data.
The following configuration options are available in the Advanced area for the CD disc type:
Check box
Read Media Catalog Number and ISRC
Reads the media catalog number, a globally unique number for compilations, and the ISRC (International Standard Recording Code), a globally unique number for audio recordings.
Check box
Use jitter correction
Jitter corrector removes scratches from audio and video files. 
The following configuration options are available in the Error Correction area for DVD and Blu-ray Disc:
Option button
Read with error correction
Performs error correction while reading. In the process, the checksum of a corrupt sector is adjusted so that the sector in itself is consistent.
Input field
Read retry count
Establishes the number of attempts that are made to correct errors.
Option button
Fast reading without error correction
Performs fast reading without error correction.
The following configuration options are available in the Dealing with Non-Correctable Reading Errors area for DVD and Blu-ray Disc:
Check box
Ignore read errors
Ignores read errors on the original disc.
If this check box is cleared, Nero Burning ROM may interrupt the burn process depending on the type of error.

 

 
 
With certain disc formats such as video CD and audio CD, read errors often have little or no impact because they are not perceptible when the CD is played.
 
Subchannel data
Subchannel data on a disc contains additional information, such as CD Text or information on positions.
Jitter
Jitter refers to an abrupt and undesired change in the signal characteristics. Small gaps occur in the data stream as a result. Audio correction synchronizes the data by overlapping the sectors. This way, the gaps are not audible.
