can only perform one burn on them and after which you cannot burn them or reuse them again. you can can burn them and reuse them as many times as you like. The RW simply means the discs are re-writable i.e. There are two types of blank CDs and DVDs – CD-R or CD-RW and DVD-R or DVD-RW. For example, the VersionTech USB DVD CD Burner SuperDrive does exactly the same job as the Apple SuperDrive but costs just $29.99. You can buy external Apple SuperDrives for around $70 but you can also use just about any external CD/DVD burner. You’ll therefore need to purchase an external SuperDrive or CD/DVD recorder that you can connect to your Mac’s USB ports. However, since the beginning of 2011, Apple phased them out and Macs no longer include an internal CD or DVD player.
If your Mac was built before 2011, it will already have an internal Apple SuperDrive (or if it’s really old, an Apple Combo drive) which can burn CDs and DVDs.
