Once you have your blank media on your computer, there are several ways to burn a CD using the built-in CD burning features of Mac OS X.
You can write up to 700 MB of data to a CD. CD-Rs can only be written to once, while CD-RWs will allow you to reuse the media.
Before you can backup your files by burning them to a CD, you will first need to purchase some blank media. This is a good way to back up your files. It is possible to transfer(“burn”) files to a CD using your Mac’s built-in CD-R/CD-RW drive.
