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. DVD burner lasers often peak at about 100-400 mW in continuous wave (some are pulsed).Ĭomputer-based DVD (Digital Versatile Disc) drives ĭVD recorder drives are standard equipment in many computer systems on the market, after being initially popularized by the Pioneer/ Apple SuperDrive aftermarket drives can cost as little as $20. The faster the writing speed is rated, the stronger the laser. The reading laser is usually not stronger than 5 mW, while the writing laser is considerably more powerful. Recorders use a laser (usually 650 nm red) to read and write DVDs. In practice, this is largely confined to computer-based DVD recorders, since standalone units generally record in real time, that is, 1X speed.
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. Most current DVD drives support both the + and - standards, while few support the DVD-RAM standard, which is not directly compatible with standard DVD drives. Originally, DVD recorders supported one of three standards: DVD-RAM, DVD-RW (using DVD-VR), and DVD+RW (using DVD+VR), none of which are directly compatible. The first DVD recorders appeared on the market in 1999-2000. Standalone DVD recorders, alongside Blu-ray recorders, have been relatively scarce in the United States due largely to "restrictions on video recording" and piracy concerns.
However, these DVD recorders can still record analog audio and analog video. NTSC DVD recorders are undergoing a transformation, either adding a digital ATSC tuner or removing over-the-air broadcast television tuner capability entirely.

The US Federal Communications Commission (FCC) has interpreted this rule broadly, including apparatus such as computers with TV tuner cards with video capture ability, videocassette recorders and standalone DVD recorders. Such devices are available as either installable drives for computers or as standalone components for use in television studios or home theater systems.Īs of Maall new tuner-equipped television devices manufactured or imported in the United States must include an ATSC tuner. A DVD recorder is an optical disc recorder that uses optical disc recording technologies to digitally record analog or digital signals onto blank writable DVD media.
