This ultra portable, USB Powered external DVD-RW drive by Samsung reads and writes all DVD formats as well as all CD formats. The drive connects to your USB 2.0 port for high speed burning and portability and does not need to be plugged in to an electrical outlet (in most cases). With Power CD+G Burner software and the included quick start guide, you can copy all your CD+G discs, rip CD+G discs to your hard drive, and burn any MP3+G or BIN tracks from your hard drive (like those available from CAVS or Tricerasoft) to blank music CD-R media, making discs that will play in virtually any karaoke player, guaranteed!
