iMac keeps ejecting disc

Hi,
My iMac ejects blank discs when I try to burn music in Tunes or when I insert a music CD to play it.
The disc spins around for about 15 seconds, then it gets ejected. I made sure the surface of the discs were clean and that I was burning from a "playlist," all to no avail.

I was successful at playing a movie in iDVD, though, so I'm baffled.
Any ideas?

Thanks,
Brad

Try a DVD drive cleaner
by mrmacfixit Forum moderator / September 3, 2010 10:34 AM PDT

run it a couple of times and see if you can burn then.

Sounds like a dirty optical drive but...it could be worse.

Tried this, but

P,
I tried the cleaning disc (Maxell CD & DVD Laser Lens Cleaner) a couple of times, but it keeps ejecting itself shortly after inserting it into the disc drive.

I saw this awhile back. Somebody said to trash the following folders:
*com.apple.kernelcaches (from System/Library/Caches)
*extensions.kextcache (from System/Library
*CD Info.cidb (from ~Home/Library/Preferences)
*Restart

Worth trying or a waste of time?

Thanks anyway!

Can you give me the steps on what i have to do to deleting o trash the following folders:
*com.apple.kernelcaches (from System/Library/Caches)
*extensions.kextcache (from System/Library
*CD Info.cidb (from ~Home/Library/Preferences)


I have no idea how to get into this step. I have encountered this exact problem but the lens cleaner did not work and also tried resetting PRAM and NVRAM

I have an iMac, Processor 3.06 GHz Intel Core i3

Please help

You do NOT delete any folders
by mrmacfixit Forum moderator / March 13, 2013 9:41 PM PDT

Do the following:

From the Finder menubar click on GO
If you see the choice of Library, click it
If you do not see the word Library, hold down the option key.
Choose Library.

Find the Preferences folder. (Not the Preferences Panes)
Find the CD Info.cidb file and drag it to the desktop
Close all the windows
Reboot
Try putting in a blank CD now
