DVR with built-in DVD recorder.

A DVD recorder is an optical disc recorder that records video onto blank writable DVD media. Such devices are available as either installable drives for computers or as standalone components for use in studios or home theater systems. Currently in the U.S. DVD recorders are under going a transformation adding a digital ATSC tuner if it has a tuner as mandated by the FCC.

Technical information

Originally, DVD recorders supported one of three standards: DVD-RAM, DVD-RW, and DVD+RW, none of which are directly compatible. As a general rule, however, most current drives support both the + and - standards, while few support the DVD-RAM standard, which is not directly compatible with standard DVD readers. DVD (commonly known as Digital Versatile Disc or Digital Video Disc) is an optical disc storage media format that can be used for data storage, including movies with high video and sound quality. ...

Recording speed is generally denoted in values of X (similar to CD-ROM usage), where 1X in DVD usage is equal to 1.321 MB/s, roughly equivalent to a 9X CD-ROM. In practice, this is largely an issue confined to computer-based DVD recorders, since standalone units generally record in real time, that is, 1X speed. The CD-ROM (an abbreviation for Compact Disc Read-Only Memory (ROM)) is a non-volatile optical data storage medium using the same physical format as audio compact discs, readable by a computer with a CD-ROM drive. ... It has been suggested that Real-time computing be merged into this article or section. ...

DVD recorders use a laser (usually 650 nm red) to read and write DVDs. The reading laser is usually not stronger than 5 mW, while the writing laser is considerably more powerful. The faster the writing speed is rated, the stronger the laser is. DVD burner lasers often peak at about 100 mW in CW (225 mW pulsed). Some laser hobbyists have discovered ways to extract the laser diode from DVD burners.

Computer-based DVD drives

DVD recorder drives have become standard equipment in many, though not all, computer systems currently on the market, after being initially popularized by the Pioneer/Apple SuperDrive; aftermarket drives as of early 2007 can cost as little as $30. DVD recorder drives can be used in conjunction with DVD authoring software to create DVDs near or equal to commercial quality, and are also widely used for data backup and exchange. As a general rule, computer-based DVD recorders can also handle CD-R and CD-RW media; in fact, a number of standalone DVD recorders actually use drives designed for computers.

Most internal drives are designed with parallel ATA interfaces, with serial ATA becoming more readily available. External drives almost always use USB 2.0 or IEEE 1394.

DVD recorder drives are required to respect DVD region codes when reading a disc, but do not impose a region code on written discs unless the code has specifically been written into the disc's content. DVD Regions Each DVD-Video disc contains one or more region codes, denoting the area(s) of the world in which distribution and playback are intended. ...

DVD duplication systems are generally built out of stacks of these drives, connected through a computer-based backplane. A backplane is a circuit board (usually a printed circuit board) that connects several connectors in parallel to each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus. ...

Standalone DVD recorders

When the standalone DVD recorder first appeared on the Japanese consumer market in 1999, these early units were very expensive, costing between $2500 and $4000 USD. However, as of early 2006, DVD recorders from notable brands are selling for $150 USD and €100 or less, with even lower "street prices". Early units supported only DVD-RAM and DVD-R discs, but the most recent units can record to all major formats DVD-R, DVD-RW, DVD+R, DVD+RW, and DVD+R DL. Some models now include hard disc-based digital video recorders (DVRs) to improve ease of use. Standalone DVD recorders generally have basic DVD authoring software built in; however, the appearance of the finished DVD is very basic and usually completely under the control of the unit. 1999 (MCMXCIX) was a common year starting on Friday, and was designated the International Year of Older Persons by the United Nations. ...

Some believe that DVD recorders will supersede the videocassette recorder (VCR), while others believe that they will remain specialty items as digital video moves to network distribution. The video cassette recorder (or VCR, less popularly video tape recorder) is a type of video tape recorder that uses removable cassettes containing magnetic tape to record audio and video from a television broadcast so it can be played back later. ...

DVD recorders have several technical advantages over VCRs, including:

• Superior video and audio quality
• Easy-to-handle and smaller form-factor disc media
• Random access to video chapters without rewinding or fast-forwarding
• Onscreen multilingual subtitles and labeling not available on VCRs
• Reduced playback wear and tear
• High-quality digital copying, with little or no generation loss
• Improved editing, at least on rewritable media
• Playlisting
• No risk of accidentally recording over existing content or unexpectedly running out of space during recording
• Easy to find recordings due to chapter menus

However, an inconvenience exists in which DVDs recorded with DVD recorders must be finalized to view in other DVD players. (This disadvantage does not apply to DVD-RAM or DVD+RW discs, which require no finalization due to their 'random access' nature.) Also, the implementation of MPEG-2 compression used on most standalone DVD recorders is required to compress the picture data in real time, producing results that may not be up to the standard of professionally rendered DVD video, which can take days to compress. Generation loss refers to the loss of quality between subsequent copies of data. ... Finalizing an optical disc (the term is most frequently applied to DVD recordable media) is the process of writing out support data such as DVD menus, directory data, and the like to an optical disc in order to make it playable on a system other than the one it was...

8cm miniDVDs are widely used on some digital camcorders, primarily those meant for a consumer market ("point and shoot"); such discs are usually playable on a full-sized DVD player, but may not record on a full-sized DVD recorder system. Though popular for their convenience (in the manner of VHS-C), DVD camcorders are not considered suitable for more than casual use due to the much higher level of compression used compared to MiniDV and the difficulty of editing MPEG-2 video.

Comparison of 2007 ATSC DVD recorders

DVD Recorders produced in 2007 are required to have a built in ATSC digital tuner, and so far all currently available DVD recorders do not pass the native HD signal; instead, the signal is down scaled and sometimes then upscaled. Therefore you will get better video quality from a dedicated ATSC tuner such as the Samsung DTB-H260F if you have an HDTV.
