DVD media comes in several formats; including DVD+R (recordable DVD), DVD-R, DVD+RW (re-writeable DVD), DVD-RW, DVD-RAM (random access memory) and DVD-ROM (read only memory).

What are the differences among the formats?
The differences are as follows:

• DVD-R and DVD+R record data one time only, then the disc is only readable
• DVD-RW, DVD+RW and DVD-RAM allow you to record and erase data multiple times
• DVD-ROM only reads data; you cannot save to this disc

What does the plus and dash found in the format mean?
When DVD media technology was first developed, the plus and dash formats used different writing and reading specifications. Today, most DVD writers and readers now work with no noticeable performance differences between plus and dash formats. Check with your manufacturers’ suggestion of DVD format for the best compatibility—especially in older technology.

In relation to DVDs, what does Double Layer recording mean?
Recording using a double layer DVD (also referred to as Dual Layer DVD by the +RW alliance) nearly doubles disc storage capacity with two recording layers on a single-sided disc. Pioneering this technology, Verbatim’s parent company was the first to bring double layer DVD media to the market. Verbatim’s DVD+R DL are considered to be one of the best DL media available, featuring almost no compatibility issues, along with quick and flawless burn speeds.

So how do I know which DVD to use?
Recordable DVD media is a natural choice for data archiving and backup. Choosing a DVD+R or DVD-R is ideal, as these write once discs prevent contents from being erased or mistakenly replaced. Also, to extend the life of your DVD disc, consider Archival Grade DVDs, which include a gold layer that is naturally resistant to corrosion and offers greater protection than standard silver discs. DVDs are also a great option simple data backup. Using DVD+RW/DVD-RW or DVD+RAM/DVD-RAM re-writable media allows content to be added and edited as the information changes.
