This document has important information regarding the optical drive that came with your computer.
Your optical drive supports both normal and "High-Speed" (greater than 4x) CD-R and CD-RW media with a 74-minute media capacity.
If you have a SuperDrive, it can read but cannot write to high-speed CD-RW media.
When handling discs, be careful not to leave fingerprints, place other materials on the discs, or add labels to the discs that may cause them to become unbalanced when spinning.
Use CD-R discs for recording audio CDs, because most audio CD players cannot read CD-RW discs.
