Thanks for the suggestions. Unfortunately, they didn't solve the problem. (I thought that when you start up in Safe Boot mode, the Mac repairs disk permissions during the boot sequence. Was I wrong about that?)
Anyhow, I repaired disk permissions, and I clicked the option to ignore the CD when it's inserted - and I still get the same error message when I try to burn a CD.
Does anybody have any other suggestions? (Help! I am unable to burn CDs now!)

See What is Safe Boot, Safe Mode? (Mac OS X)
In terms of your specific issue: Go to Apple Menu > System Preferences > Accounts. Select the account in which you are experiencing this issue the go to Login Items. Scan the list for anything that might be tying up the CD burner.
Thanks for the suggestion. I removed iTunes from the list of applications that launch at start-up and then rebooted the computer. I installed a CD and tried to burn a playlist from iTunes and I got the same error message. I.e. the problem still exists.
Any other ideas as to what could be causing this?
This suggestion may ruffle a few feathers on the power users, but try running Onyx. Run 'Automation' in the Onyx pane and see if it still misbehaves.
Onyx - http://www.titanium.free.fr/pgs2/english/download.html
Thanks for the suggestion. I downloaded OnyX and ran the Automation option. After it finished I rebooted the computer and attempted to burn a music CD. I got the same result - an error message that another device is using the burner.
Then I followed the next person's suggestion, and something interesting happened.... (see my next post).
Good suggestion. It didn't solve my problem - but it did lead to a new error message.
I told iTunes to burn a CD, and I waited for it to prompt me to insert a blank disc. After I inserted the disc, iTunes started trying to burn the disc, then spat it out after a few seconds. An error message popped up that says:
"The attempt to burn a disc failed. The device failed to calibrate the laser power level for this media."
Now that's an interesting error message. Any ideas about this?
You may need to set the burn speed lower, or use different media.
What speeds are you using now?
Look in iTunes Preferences, and on the media.
Review the info here You're unable to burn a CD in iTunes.
Thanks again for the suggestions and support. (The Mac community is really great.)
I read the article that you referenced. All of my settings/preferences were set as that article recommends, except that I had the burn speed set to 4x. I reduced it to 1x - the slowest possible speed - and then inserted the blank disc when prompted. I got the same error message as last time - the one about "unable to calibrate the laser".
This is a long shot, but, if you know how to enable them again, delete all of the Login Items, except iTunesHelper.
Quit all running applications.
Navigate to HD > Users > Your Account > Library > Preferences.
In that folder, locate, and move to the Trash:
See if it works now.
If so, you can empty the Trash.
