A DVD writer lets you burn video, music and data to 4.7- and 8.5-gigabyte recordable DVDs. You can permanently save data to a DVD-R disc or use a rewritable DVD-RW to temporarily store files. Every DVD recorder doubles as CD burner, and many also feature advanced features such as disc labeling and buffer underrun prevention. A software program known as “firmware” provides burning instructions from the computer’s operating system. You can update the firmware to repair a drive or fix a compatibility issue.
