Based on the above discussion, CD-RW or DVD-RW disks are the best choice, right?
If you are using a CD or DVD to back up data, a CD-R or DVD-R may be a better choice because the data is more permanent. Also, if you are creating music CDs or DVD movie disks that will be used on a CD or DVD player, the RW variety disks may not work on these players. Lastly, if you are creating disks to give to someone else, remember that not everyone has a CD or DVD burner in their computer. The R disks have the widest compatibility.
