The Apple iMac comes with a DVD drive capable of both playing and burning, or recording, DVDs. You can use DVDs to store files, such as music or documents, or you can create your own custom DVD movies complete with personalized menus. The iMac lets you burn DVDs both through the Finder and through iDVD, which is Apple’s application for creating DVDs. Use the Finder to burn data DVDs for backing up or storing files; use iDVD to create a personalized DVD that will play on DVD players. Writer Bio
