Introduction MEDIA Making the Iso Image Burning the Image Burning CDs DVD-R/RW Burning DVD+R/RW SEE ALSO - man pages
This Document is for users wishing to burn CDs or DVDs on the computer science lab machines basie and armstrong. This Document covers the following commands: mkisofs cdrecord growisofs
There are several different kinds of media with which the lab burners are compatible: CD-R, CD-RW, DVD-R, DVD-RW, DVD+R, DVD+RW
You may skip the rest of this section if you are already familiar with the differences between these media types.
CD-R is CD Recordable media, these are write only once with a cdrom capacity. (650MB or 700MB). The disc label or packaging will have "CD- R" written on it.
CD-RW is CD Recordable-Rewritable media, these are rewritable media with a cdrom capacity. (650MB or 700MB) The disc label or packaging will have "CD-RW" written on it.
DVD-R is DVD Recordable- media, these are write once media with a capacity of 4.7GB. The disc label or packaging will have "DVD-R" written on it.
NOTE: DVD-R is not the same as DVD+R, although they look identical, they are technically two different type of discs. This important, see the section on burning the iso image.
DVD-RW is DVD Recordable-Rewritable, these are rewritable media with a capacity of 4.7GB. The disc label will have a "DVD-RW" written on it.
DVD+R is DVD Recordable+ media, these are write only once media with a capacity of 4.7GB. The disc label will have a DVD+R on the disc.
DVD+RW is a DVD Recordable+Rewritable media, these are rewritable media with a capacity of 4.7. The disc label or packaging will have "DVD+RW" written on it.
NOTE: DVD-RW is not the same as DVD+RW, although they look identical, they are technically two different type of discs. This important, see the section on burning the iso image.
Making the Iso Image
If a prebuilt image is being used (such as Fedora core isos) skip this section.
To create an image we will create an image with the mkisofs command.
command: mkisofs -l -J -L -r -v -o image.iso path/to/source/
Example: mkisofs -l -J -L -r -v -o transcode.iso /s/arm- strong/a/tmp/transcode
This command will create an image named transcode.iso in the current directory with the root directory of the cd being /s/armstrong/a/tmp/transcode All files and directories in this directory are recursively put in the image transcode.iso
A note about images: It is recommended that images are made in the temporally burning directory. On armstrong it is /s/armstrong/a/tmp and on basie it is /s/basie/a/tmp These are directories are local disks to each of these machines. The Next section will explain why.
Using a Microsoft Windows based cd-image program, such as Nero or Easy CD Creator also works. The image created must be a iso9660 image (usually the save .iso option in most programs work)
Burning the Image
Which linux command to burn your image depends on which type of media. To avoid bad burn discs, use the local temp directories (/s/arm- strong/a/tmp or /s/basie/a/tmp) and burn when the machines are mostly idle. To do this, use the top command and see if the cpu time is less than 20 percent. This will help in having a good burn.
Burning CDs and DVD-R/RW For CDs and DVD minus media (DVD-R, DVD-RW) use cdrecord
command: cdrecord -v speed=4 dev=/dev/dvdrw -sao -data image.iso
example: cdrecord -v speed=4 dev=/dev/dvdrw -sao -data transcode.iso
this will burn the image transcode.iso to the cd or dvd disc. transcode.iso must be in the current directory
For DVD plus media (DVD+R, DVD+RW) use growisofs
command: growisofs -Z /dev/hdd=/path/to/image.iso -dvd-compat -speed=2.4
growisofs -Z /dev/<device_name>=/s/armstrong/a/transcode.iso -dvd-compat -speed=2.4
in this example, the image transcode.iso is being burned from the tem- pory directory on armstrong. This will burn the image to the DVD+R/RW disc
