That disk burning error message can cover a few problems. The "Failed to calibrate laser power level" message was meant to indicate that your CD/DVD burner was unable to find the right settings for the blank media you are using. So the first thing to try is different blank media. Do not test with other disks from the same group or spindle, but instead try different brands of CD-R banks. Borrow or trade some blank discs with friends for a good crosscheck of media. See if your blank discs work in your friends' computers and see if theirs work in your MacBook Pro. If you fail to burn any CDs in your MacBook Pro, regardless of how many different brand discs you use, it is probably is a drive or driver issue.
     The lens-cleaning discs with fibers that actually make contact with the lens are bad news. They can easily scratch your lens and make your problems worse. I recommend the compressed-air method. It's tricky not to blow more dust onto the lens than what you started with.
      The last possibility is that the hardware has failed and the optical drive may need to be replaced. If you determine that the two possible culprits above are not to blame, take your MacBook Pro to a local Apple Authorized Service Center.
