'''Burn speed''' is one of the possible factors related to this problem. In '''iTunes->Burn Playlist to Disc->Choose Options:''' Choose the option from the Preferred Speed pop-up menu, '''Change the CD recording speed''', ''Specify a burn speed that is lower than the maximum speed rating for your optical drive.'' (try 1/2 that maximum speed )
'''Other possible variables:'''
BE sure the disc is clean. Wipe the shiny surface with a soft, damp cloth, working from center to edge.
Do not move, bump, or shake the computer while the disc is being burned.
Use blank discs that are rated for the burn speed of your drive, or consider using a different brand of disc (excessively cheap or off-brand optical disks are known to have problems).
Quit all open applications you’re not using.
'''If your startup disk is nearly full,''' try to free up space on it. The amount of free space on the startup disk needs to be greater than the amount of data you’re burning. Erase unnecessary files. Back up files you don’t use often, and then remove them.
Repair your startup disk with Disk Utility, in the Utilities folder in the Applications folder.
If none of the above possible fixes work you could have a damaged optical disk drive.
