DVD-R

(DVD-Recordable) A write-once (read only) DVD disc for both movies and data endorsed by the DVD Forum. DVD-Rs are often called "DVD Dash Rs" or "DVD Minus Rs" to distinguish them from the competing "Plus R" format (see DVD+R).

DVD-Rs are the DVD counterpart to CD-Rs and use the same dye-layer recording technology to "burn" the disc. Pioneer was the first to introduce DVD-R drives, which recorded 3.95GB. By 2000, the capacity was increased to the industry standard 4.7GB. A dual-layer drive (DVD-R DL) increases capacity to 8.5GB.

In practice, the term "DVD" refers to all DVD formats. The phrase "burn the DVD" really means "burn the DVD-R or DVD+R."

DVD-R for Authoring, DVD-R for General
In 2000, DVD-R was split into two types to deal with copy protection. The original DVD-R, which uses a 650 nm recording wavelength, was dubbed "DVD-R for Authoring." A different format with copy protection that records at 635 nm is called "DVD-R for General." Although DVD-R(a) and DVD-R(g) can read each other's format, they cannot write each other's format.

A Small Fortune in the Beginning
DVD-R machines (DVD burners) cost as much as USD $17,000 in their first incarnations back in 1997 but dropped to less than $25 two decades later. See DVD, DVD storage capacities, DVD+R, CD-R and optical disc.

DVD-R media provides an archival life expectancy that is equal to or better than CD-R; for this reason, the format is suitable for long-term archival of any information that can be stored digitally.
This allows automated retrieval of recorded DVD-R volumes in networked environments with a six to seven-fold increase in storage density as compared with CD-R technology.
In this case, each side must be read directly by flipping the disc over, as the DVD-R format does not currently support dual layer technology.
