What's the difference between DVD-R and DVD+R?

DVD-R and DVD+R

DVD-R was the first to be introduced and is still the most widely used format among professional users. (2006). DVD+R is widely sold in retail outlets and has become more popular among home users.
DVD+R was introduced in early 2002 as a competing format. ---- Proponents claimed better compatibility among readers, although tests show that compatibility is roughly equal.
Hybrid drives that can handle both formats, usually labeled "DVD±RW", are very popular since there is not a single standard for recordable DVDs. There are a number of significant technical differences between the dash (also sometimes called "minus") format and the plus format, though most consumers would not notice the difference.

Review Verbatim LightScribe 8X DVD+R DL

Leveraging many of the same technologies that set the standard for high-speed DVD+R Double Layer (DL) disc performance, reliability and compatibility, Verbatim has announced the world’s first LightScribe® 8X DVD+R Double Layer (DL) discs. At 8X speed, the industry’s fastest DVD DL burning speed, an entire 8.5GB single-sided disc can be filled to capacity in 15 minutes or less.LightScribe certified, Verbatim’s new double layer media is fully compatible with LightScribe-enabled drives, duplicators and the latest software licensed by Hewlett-Packard. When combined, the same drive that burns content to the data side of the disc can be used to burn silkscreen-quality monochrome labels directly on the label side of the discs. The discs are produced with LightScribe Media Version 1.2 coating technology on the label side to provide enhanced contrast for photos, graphics, images and text.By offering compliance that exceeds the DVD+R DL standard, users also have the assurance that Verbatim’s new LightScribe media is compatible with the new multi-format drives and duplicators that support 8X DVD+R DL technology and most DVD playback devices. The increased storage capacity required by digital content — especially HD video - and the volumes of Internet content that are being downloaded are driving the demand for higher capacity storage. With two recording layers on a single side, Verbatim’s new media nearly doubles the storage capacity of a DVD from 4.7GB to 8.5GB. The higher capacity will enable businesses, content developers and consumers to store up to 3.5 hours of DVD-quality videos, about one hour of HD video or 8.5GB of data - without having to flip the disc. The capacity and 8X performance that these discs provide also make them ideal for backups and archiving.

Verbatim: World's first supplier of single-sided 30 GB HD DVD Dual Layer

Eschborn / Egham (UK), August 2007 – Verbatim and its Japanese parent company Mitsubishi Kagaku Media (MKM) will be unveiling the world’s first single-sided dual-layer HD DVD-R. The twin-layer storage medium offers a capacity of 30 Gigabytes and can be written to at 1 x speed. The European official market launch will be held at the end of August at the IFA in Berlin.

Verbatim is the first brand to launch a single-sided, writeable dual-layer HD DVD-R with 30 GB of data capacity, which is compatible with current drives and burners in the market. The new, high-definition medium offers space for up to four hours of film material in HD quality. “The growing popularity of high-definition TV and programmes in particular is pushing up demand for recording media with a high storage capacity for high-resolution content," says Torsten Leye, Marketing Manager Optical at Verbatim.

Top-quality development and production for high-definition media
The new HD DVD-R DL 30 GB’s proven AZO recording layer technology ensures a high degree of laser sensitivity and error-free reading of the data. Verbatim also uses the DVD-R DL 2P manufacturing process in the production of the HD DVD-R DL. With this method, the two layers are produced one after the other on one side of the HD DVD. Outstandingly precise stampers and precision moulding equipment ensure perfectly flat HD DVDs that comply with all the standards for high recording quality.

“In the development of the dual-layer HD DVD-R, we were able to rely on both our technology and our production expertise that we gained in producing the world's first writeable, single-sided dual-layer recordable DVD, as well as in our expertise in the manufacture of single-layer HD DVD Rs,” says Leye. The new media not only offers a significantly higher storage capacity, but also excellent burner compatibility and maximum reliability for long-term data archiving.”

“We have been satisfying our customers’ needs for many years through the ongoing development of high-quality and reliable storage media,” says Leye. “Today, we are the first to market with the new dual-layer HD DVD-R 30 GB and thus well-positioned in a sector that will continue to grow strongly in years to come.”
