- In computing, an optical disc drive (ODD) is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from discs, but recent drives are commonly both readers and recorders, also called burners or writers. Compact discs, DVDs, and Blu-ray discs are common types of optical media which can be read and recorded by such drives. Optical drive is the generic name; drives are usually described as "CD" "DVD", or "Blu-ray", followed by "drive", "writer", etc.

The burning process of optical disc drives consists of creating or obtaining an image and writing it to an optical medium. The image may in principle be any data file. If you want to mount the resulting medium, then it is usually an ISO 9660 filesystem image file. Audio and multi-media CDs are often burned from a BIN file, under control of a TOC file or a CUE file which tell the desired track layout.
Install burning utilities
If you want to use programs with graphical user interface, then follow this link to the list of GUI programs.
The programs listed here are the back ends which are used by most free GUI programs for CD, DVD, and BD. They are command line oriented. GUI users might get to them when it comes to troubleshooting or to scripting of burn activities.
You need at least one program for creation of filesystem images and one program that is able to burn data onto your desired media type.
Available programs for ISO 9660 image creation are:
The traditional choice is
Available programs for burning to media are:
cdrdaofrom package (CD only, TOC/CUE/BIN only)
growisofsfrom package (DVD and BD only)
wodimfrom package (CD only, DVD deprecated)
The traditional choices are
wodim for CD and
growisofs for DVD and Blu-ray Disk. For growisofs and BD-R see the bug workaround below.
For writing TOC/CUE/BIN files to CD, install
The free GUI programs for CD, DVD, and BD burning depend on at least one of the above packages.
xorrisofs all three support the genisoimage options which are shown in this document.
wodim all three support the shown wodim options. Program
xorrecord supports those which do not deal with audio CD.
The installed files of packages makepkg and install with pacman. Pacman wrappers may resolve to cdrkit instead.and are in conflict. If you want to install cdrtools, make sure that you build a package using
Learning the name of your optical drive
For the remainder of this section the name of your recording device is assumed to be
Check this by
$ wodim dev=/dev/cdrw -checkdrive
which should report "Vendor_info" and "Identification" of the drive.
The next guess could be
If no drive is found, check whether any
/dev/sr* exist and whether they offer rw-permission to you or your group.
/dev/sr* exists then try
$ modprobe sr_mod
CD-RW media usually need to be erased before you can write new data on it. To blank CD-RW medium use this command:
$ wodim -v dev=/dev/cdrw -blank=fast
As you might have guessed, this blanks your medium really fast, but you can also use some other options, just replace the word fast with one of the following:
- blank the entire disk
- blank the entire disk
- blank the entire disk
- minimally blank the entire disk (PMA, TOC, pregap)
- minimally blank the entire disk (PMA, TOC, pregap)
- blank a track
- unreserve a track
- blank a track tail
- unclose last session
- blank last session
Burning an ISO image
To burn an ISO image run:
$ cdrecord -v dev=/dev/sr0 isoimage.iso
Verify the burnt ISO image
You can verify the integrity of the burnt CD to make sure it contains no errors. Always eject the CD and reinsert it before verifying.
First calculate the md5sum of the original ISO image:
$ md5sum isoimage.iso
If the CD was burnt in DAO (Disc At Once) mode by passing the -dao option to cdrecord you can calculate the md5sum of the burnt CD as follows:
$ md5sum /dev/sr0
If the CD was burnt in TAO (Track At Once) mode it can be verified with dd and md5sum. You need to know the number of sectors to check. You can calculate this by dividing the size of the ISO file by 2048, but for your convenience this is included in the output of cdrecord:
Track 01: Total bytes read/written: 90095616/90095616 (43992 sectors).
Then check if this matches the md5sum of the burnt image, replacing "count" with the number of sectors:
$ dd if=/dev/sr0 bs=2048 count=43992 | md5sum
43992+0 records in 43992+0 records out 90095616 bytes (90 MB) copied, 0.359539 s, 251 MB/s e5643e18e05f5646046bb2e4236986d8 -
Burning an audio CD
Create your audio tracks and store them as uncompressed, 16-bit stereo WAV files. To convert MP3 to WAV, ensure
cd to the directoy with your MP3 files, and run:
$ for i in *.mp3; do lame --decode "$i" "$(basename "$i" .mp3)".wav; done
In case you get an error when trying to burn WAV files converted with lame try decoding with:
$ for i in *.mp3; do mpg123 --rate 44100 --stereo --buffer 3072 --resync -w $(basename $i .mp3).wav $i; done
Name the audio files in a manner that will cause them to be listed in the desired track order when listed alphabetically, such as
Use the following command to simulate burning the wav files as an audio CD:
$ wodim -dummy -v -pad speed=1 dev=/dev/cdrw -dao -swab *.wav
In case you detect errors or empty tracks like:
Track 01: audio 0 MB (00:00.00) no preemp pad
try another decoder (e.g. mpg123) or try using cdrecord from thepackage.
Note thatalso contains a cdrecord command but it is just a softlink to wodim. If anything worked you can remove the dummy flag to really burn the CD
To test the new audio CD, use MPlayer:
$ mplayer cdda://
Burning a bin/cue
To burn a bin/cue image run:
$ cdrdao write --device /dev/cdrw image.cue
Making an ISO image from an existing CD
To copy an existing CD just type:
$ readom -v dev=/dev/cdrw f=isoimage.iso
# umount /dev/cdrwReplace /dev/cdrw with /dev/cdrom if it's a CDRom.
You do not want to use dd or cat as they provide no error checking, but for reference here are those commands:
$ dd if=/dev/cdrw of=/home/user/isoimage.iso
or with cat:
$ cat /dev/cdrw > isoimage.iso
Or use the
readcd program (which is now a symlink to readom), also in the
$ readcd -v dev=/dev/cdrw -f isoimage.iso
If the original CD was bootable it will be a bootable image.
TOC/CUE/BIN for mixed-mode disks
ISO images only store a single data track. If you want to create an image of a mixed-mode disk (data track with multiple audio tracks) then you need to make a TOC/BIN pair:
$ cdrdao read-cd --read-raw --datafile IMAGE.bin --driver generic-mmc:0x20000 --device /dev/cdrom IMAGE.toc
Some software only likes CUE/BIN pair, you can make a CUE sheet with
toc2cue (part of
$ toc2cue IMAGE.toc IMAGE.cue
Making an ISO image from existing files on hard disk
To make an iso image just copy the needed files to one folder, then do:
$ mkisofs -V volume_name -J -r -o isoimage.iso ~/folder
Mounting an ISO image
To test if the ISO image is proper, you can mount it (as root):
# mount -t iso9660 -o ro,loop=/dev/loop0 cd_image /cdrom
You have to first load the loop module:
# modprobe loop
See also Mounting images as user for doing this without root privileges.
Converting to an ISO image
To convert an
ccd image, you can use :
$ ccd2iso ~/image.img ~/image.iso
Writing (or "burning") DVDs requires a different approach than burning CDs. DVDs offer much higher capacities, and the standard CD writing tools will not suffice.
This guide covers a narrow scope for now: writing data onto DVDs using the command line.
- You still need the standard CD writing tools known as (which can be replaced by , if desired).
- You also need the new DVD writing tools known as official repositories. found in the
- Do not install the package known as . It conflicts with , and is the superior DVD writing package.
dvd+rw-toolsseems to be stalled for the past 5 years (the last release was in 2008) provides all the functionality of , as growisofs depends on mkisofs. Also the development of
This guide will use the command
growisofs from the package. If you have ever written CDs from the command line before, you will know the process of first creating an iso9660 file (
mkisofs), and then burning it to CD (
growisofs merges these steps, so you do not need extra storage space for the ISO file anymore. Another advantage is that multisession writing has been simplified.
Essentially, writing a new DVD follows this procedure:
$ growisofs -Z /dev/sr0 -r -J /path/to/files
/dev/sr0 is your DVD writer device.
To continue a DVD (write an additional session), you use:
$ growisofs -M /dev/sr0 -r -J /path/to/files
To burn an ISO image to disc, use:
$ growisofs -dvd-compat -Z /dev/sr0=/path/to/iso
To create a video DVD, use the following:
$ growisofs -Z /dev/sr0 -dvd-video /path/to/video
- start at the beginning of the DVD using the following device
- start after the last session on the disc using the following device
- Rock Ridge support with sane permission settings (recommended, extended Unix info)
- Joliet support (recommended, extended info for Windows NT and Windows 95)
-rwill choose different permissions than the real ones; to use the exact permissions use
-Rinstead. See the man page of
mkisofsfor more information.
growisofs has a small bug with blank BD-R media. It issues an error message after the burning is complete. Programs like
k3b then believe the whole burn run failed.
To prevent this, either
- format the blank BD-R by
dvd+rw-format /dev/cdrwbefore submitting it to growisofs
- or use growisofs option
$ readcd -v dev=/dev/sr0 -f image.isoas for CD burning, then use the
growisofsexample above to burn the ISO to a new blank disc.
Although the above might suffice for you, some users require extra settings to successfully write DVDs.
A simple DVD writing template:
$ growisofs -Z /dev/cdrw -v -l -dry-run -iso-level 3 -R -J -speed=2 -joliet-long -graft-points /files/=/path/to/files/
- as seen above, this starts a new DVD; to continue a multisession DVD, use
- increase verbosity level (more output)
- breaks DOS compatibility but allows for longer filenames
- simulate writing (remove this flag if you are sure that everything is set up correctly)
- defines how strict you want to adhere to the iso9660 standard (
-iso-level 1is very strict while
-iso-level 4is very loose)
- see above
- see above
- start burning at 2X speed
- allows longer Joliet file names
The final part needs more explanation:
This specifies that files will be stored in the subdirectory
/files rather than the DVD root. See the
mkisofs manual for details.
growisofsis basically just a front-end to
mkisofs. That means that any option for
mkisofsalso works with
growisofs. See the
mkisofsman page for details.
The process for burning re-writable discs is almost the same as for normal DVDs. However, keep in mind that virgin DVD+RW media needs to be initially formatted ("blanked") prior to usage. Blanking can be done using the program
dvd+rw-format like this:
$ dvd+rw-format /dev/cdrw
/dev/cdrw is your DVD writer device.

To play a DVD image file:
$ mplayer -dvd-device movie.iso dvd://N
To enable the DVD menu use (NOTE: you use arrow keys to navigate and the Template:Keypress key to choose):
$ mplayer dvdnav://
To enable mouse support in DVD menus use:
$ mplayer -mouse-movements dvdnav://
To find the audio language, start MPlayer with the
-v switch to output audio IDs. An audio track is selected with
-aid <audio_id>. Set a default audio language by editing
~/.mplayer/config and adding the line
alang=en for English.
With MPlayer, the DVD could be set to a low volume. To increase the maximum volume to 400%, use
softvol-max=400. The startup volume defaults to 100% of software volume and the global mixer levels will remain untouched. Using the 9 and 0 keys, volume can be adjusted between 0 and 400 percent.

Ripping is the process of copying audio or video content to a hard disk, typically from removable media or media streams.
Often, the process of ripping a DVD can be broken down into two subtasks:
- Data extraction - Copying the audio and/or video data to a hard disk
- Transcoding - Converting the extracted data into a suitable format
Some utilities perform both tasks, whilst others focus on one aspect or the other.
dvdbackup is used simply for data extraction, and does not transcode. This tool is useful for creating exact copies of encrypted DVDs in conjunction with or for decrypting video for other utilities unable to read encrypted DVDs.
dvd::rip is a front-end to, used to extract and transcode on-the-fly.
The following packages should be installed:
- : GTK front-end for , which performs the ripping and encoding
- : Software codec for DV video
- : If you want to encode your ripped files as XviD, an open source MPEG-4 video codec (free alternative to DivX)
- AUR) AUR: If you want to encode your ripped files as DivX (available in the
The dvd::rip preferences are mostly well-documented/self-explanatory. If you need help with something, see http://www.exit1.org/dvdrip/doc/gui-gui_pref.cipp.
Ripping a DVD is often a simple matter of selecting the preferred codec(s), selecting the desired titles, then clicking the "Rip" button.
FFmpeg is capable to do a direct rip in any format (audio/video) from a DVD-Video .iso image, just select the input as the *.iso image and proceed with the desired options. It also allows to downmixing, shrinking, spliting, selecting streams among other features.
HandBrake is a multithreaded video transcoder, which offers both a graphical and command-line interface with many preset configurations. The package is available in the official repositories: .
MEncoder is a free command line video decoding, encoding and filtering tool released under the GNU General Public License. It is a close sibling to MPlayer and can convert all the formats that MPlayer understands into a variety of compressed and uncompressed formats using different codecs. Wrapper programs like AUR and AUR can provide an assistive interface.
Hybrid is a multi platform (Linux/Mac OS X/Windows) Qt based frontend for a bunch of other tools which can convert nearly every input to x264/Xvid/VP8 + ac3/ogg/mp3/aac/flac inside an mp4/m2ts/mkv/webm/mov/avi container, a Blu-ray or an AVCHD structure.
A package is available in the AUR: AUR.

From Wikipedia - DVD-VR:
- The DVD-VR standard defines a logical format for video recording on DVD-R, DVD-RW, and DVD-RAM style media, including the dual layer versions of these media. As opposed to media recorded with the DVD+VR recording standard, the resulting media are not DVD-Video compliant, and will not play back in some DVD-Video players. Most DVD video recorders in the market that support DVD-R, DVD-RW, or DVD-RAM media will allow recording to these media in DVD-VR mode, as well as in a DVD-Video compliant mode. It is possible to use the DVD-VR format with DVD+R and DVD+RW media, but no examples are known other than some PC based recording utilities.
.VRO files extracted from a DVD-VR can be easily converted and splitted in regular .VOB files using the DVD-VR program.

K3b locale error
When running K3B, if the following message appears:
System locale charset is ANSI_X3.4-1968 Your system's locale charset (i.e. the charset used to encode file names) is set to ANSI_X3.4-1968. It is highly unlikely that this has been done intentionally. Most likely the locale is not set at all. An invalid setting will result in problems when creating data projects.Solution: To properly set the locale charset make sure the LC_* environment variables are set. Normally the distribution setup tools take care of this.
It means that your locale is not set well.
