With these drives you can read and record DVDs and/or CDs in all kinds of formats. Please note the difference between DVD+R and DVD-R when buying a DVD burner, often drives can write only to one of those two media types, sometimes to both. When you buy a drive that only supports one type, you will always have to be careful to choose the right writable DVD discs in the shop. Newer DVD drives also support writing to Dual Layer DVDs. This kind of discs have a storage capacity of 8.5 GB instead of the usual 4.7 GB. DVD (re)writers generally can read and write CDs also, but only some CD (re)writers can read DVDs.
