Overview

The submillimeter group currently has several CD recorders in Pasadena and at least one at the CSO. The following page is a quick summary of how to use them. For more information, see the CD-Recordable FAQ.

To create your own data CD, you will first need to create a disk image of the files you want to burn. Then you will write this disk image to the CD.

Creating a raw disk image

To create a disk image, you must first make sure all the files you want to write to the CD are in some directory. In this example, we will assume that this directory is called foo. To create the image foo.iso, issue the command

mkisofs -o foo.iso -V label -r -J -hfs foo

Burning the CD

Log into a computer with a CD recorder and copy the image file to a local disk. Typically, this will go something like

     cd /home/local
     mkdir your-login-name
     cd your-login-name
     cp ~/foo.iso .

• tenaya (Darek Lis's computer): Local disk space can be found in /home/tenaya/scratch.

       cdrecord -v speed=12 dev=1,1,0 foo.iso
  

• woodhall (Frank Rice's computer): Local disk space can be found in /home/local.

       cdrecord -v speed=12 dev=0,0 foo.iso
  

• fangorn (John Ward's computer): Local disk space can be found in /home/local.

       cdrecord -v speed=8 dev=0,0 foo.iso
  

• hapuna (SPARC in the control room at the summit): Local disk space may be available on /home/hapuna/scratch.

       cdrecord -v speed=4 dev=5,0 foo.iso
  

WARNING: Do not interrupt the recorder while it is writing the CD!

You may want to include the -multi flag if you intend to create a multisession CD, or the -dummy flag if you want to go through a dry run before writing to the cd. See the cdrecord man page for more information.

When you are done, you may eject the CD, label it, test it, delete the image file, and log out.
