A:DVD±R

Two recordable DVD formats allow single-layer data to be stored on each side of the disc -- in other words, one side of the disc can hold upto 4.38 gigabytes of information. Both DVD formats are write-once formats, and can be read with most stand-alone DVD players and with virtually all DVD-ROM drives, though DVD+R is technically slightly more advanced than DVD-R.

DVD-R DL

Known as DVD-R9, this is blank DVD media that uses Dual Layer technology. It can hold up to twice the capacity of a single layer DVD-R.

DVD+R DL

DVD+R DL is the dual layer version of DVD+R format. It's main difference to the DVD+R is that it can store upto 8.5 gigabytes on one disc side, unlike DVD+R which can only hold the same amount of data that a single layer disc can, appx. 4.38 gigabytes. This means basically that every single one-sided movie disc ever released can be stored to one DVD+R DL disc without compression or removing anything from the original disc.

DVD-RAM

DVD-RAM (DVD-Random Access Memory) media are used in computers as well as camcorders and personal video recorders. Compared with other writeable DVDs, DVD-RAM is more closely related to hard disk technology, as it has concentric tracks instead of one long spiral track.
