A DVD recorder (or a DVD burner) is a consumer electronics device that records analog or digital audio/visual (A/V) signals in a digital format onto a digital video disc (DVD). DVD recorders are distinct from digital video recorders (DVRs) in that they record onto a removable disc (the DVD) instead of a hard disk. Like a video cassette recorder (VCR), the DVD recorder has standard A/V inputs and playback functions. Like a DVD player, the DVD recorder can also be used to play many audio and video CDs.
DVD recorders first appeared on the consumer market in 1999 in Japan, and then in 2000 in the rest of the world. Early units were priced between between 2,500 and 4,000 USD. As of mid-2004, substantial increases in the quantities available and in the number of retail outlets selling DVD recorders have resulted in price reductions of approximately 90% compared to prices in 2000.
