These are some examples of sounds you might hear from your optical disc drive (these recordings were taken very close to the optical drive--the equivalent of having your ear directly next to the drive):

Note: The sample sounds may be similar to what you hear, but may not be an exact match. Different discs may make different noises in the drive. Not all discs can be read at the same speeds.

After listening to the example sounds, if you feel that your optical disc drive is making noises in excess of these examples during normal operation, please contact AppleCare for assistance.
