This is the old-fashioned command-line way to burn a CD:

From a terminal window on a linux box equipped with a CD burner:
 
   $> df -k /tmp

On systems that can report in "human readable" units (eg. 5 MB, 3KB,
etc), you canuse the -h option instead of -k, above

If 1 Gb or more is available, create an image file of the directory
you want to archive.  Do this on tmp:
 
   $> mkisofs -JrT -o /tmp/image.raw ~kate/howiedat/nling12_enc/results4 

NB - if you wish to archive data or directories that are in
different branches of a tree: eg. /data/alzheimer/howiedat/Videos +
/data/alzheimer/howiedat/fmri, you must first copy these two
directories in to one directory and then use the mkisofs command: 

   $> mkdir /tmp/kate
   $> cp -rp /data/alzheimer/howiedat/Videos/* /tmp/kate/.
   $> cp -rp /data/zlzheimer/howiedat/fmri/* /tmp/kate/.
   $> mkisofs -JrT -o /tmp/kate_image.raw /tmp/kate 

Execute the record command:
 
   $> cdrecord /tmp/image.raw

Once the burn is complete, take the CD out of the Read-Write drive
and put it in the CD-ROM drive and verify that you can mount the
disc, and find/read the data you put there.

   $> mount /mnt/cdrom
   $> cd /mnt/cdrom
   $> ls 

Verify that you can read the disk and that your files are there as
you expect them to be.  If all is well and you wish to remove the
CD, go back to your home directory and unmount the cdrom device:

   $> cd 
   $> umount /mnt/cdrom

Don't forget to remove CD from CD-ROM drive!

NB I: The machine you are working on may automagically mount the cdrom
device, in which case you read it as you would any other directory (cd
/mnt/cdrom, ls /mnt/cdrom, etc.)

NB II: Other common mount points for the CD-ROM device are:

/media/cdrom
/dev/cdrom

If you can't find the device, ask the person who manages the machine
how to specify it - if you have permission to do so.
