You can use Disk Utility or Disk Copy to burn to one CD-R disc two or more times until it is full, which is known as creating a multi-session CD.

For Mac OS X 10.4 Tiger

See this document for instructions.

For Mac OS X 10.2 through 10.3.9

To create a multi-session CD, use the Disk Copy utility to create a disk image file from which the CD is burned. Follow the steps below.

  1. Drag the item or items you wish to burn into a folder.
  2. Open Disk Copy (/Applications/Utilities/).
  3. Drag the folder onto the Disk Copy window. The Image Folder dialog appears.
  4. Choose a location for the image file using the Where pop-up menu. For simplicity, you may choose Desktop.
  5. Click Save. Wait for the image to be finished.
  6. Select Burn Image from the File menu. The image file should not be mounted.
  7. In the navigation dialog that appears, select the image you just created, then click Burn. If you have not already inserted a blank disc, you will be prompted to do so now.
  8. In the Burn Disc window, click the disclosure triangle.
  9. Select the checkbox for "Allow additional burns".

A disc burned with this setting will remain open to subsequent multi-session burns.

Additional burns on same disc

When performing additional burns on the multi-session disc, simply repeat Steps 1 to 7. The "Allow additional burns" setting selected in Steps 8 and 9 should automatically be retained for that disc on subsequent burns. Each new burn session on the disc will appear in the Finder as a separate disk, and it will have the name of the disk image file from which you burned it.
