An optical drive is suitable for reading and burning blank discs. For example, you can burn music, films, or videos to CD ROMs, DVDs, and Blu rays. When choosing an optical drive, consider which type of discs you want to burn or read. For a Blu-ray movie you need an external Blu-ray player. You can connect these external optical drives to your laptop or MacBook with a USB cable. An Apple USB SuperDrive works perfectly with a MacBook. Connect the optical drive via USB, install the drivers, and put the disc in the tray. Now you're ready to burn a CD, watch a Blu-ray movie, or install games.
