Discs burned on your drive can't be read by other... (by 3 users)

1. Try a different brand of CD-R media. Some drives like a particular brand, while others refuse to give it the time of day.
2. Make sure you have your CD-writing software set to "close the session" or "finalize" on discs you're writing.
3. Dust can affect your CD-R lens. You can clean the interior of the drive by blowing compressed air into it (with no disc inserted). You can also buy a standard audio CD player cleaning kit (see How to Troubleshoot a CD Player).
