Very simple....you should find a software package like Nero along with your burner (a burner is just another name for a rewriter), if you don't have a burning software package like Nero or similar and you aren't using Windows XP then you'll have to get your hands on one....if you use this you'll find it's very easy but to go through the steps anyway....first insert both discs then open your burning software and select Copy a disc....then select the drive with the music or data you want to copy as the source drive....then you should get some type of confirmation screen allowing you to select some variables like burning speeds etc. set these then hit go! All pretty simple once you've done it once or twice just give it a go and you'll see.
