DVD+/-R vs DVD+/-RW:
Nowadays, there are really only two "families" of DVD, the "minus" formats (DVD-R, DVD-RW) and the "+quot; formats (DVD+R, DVD+RW). All of these are for data. Some have R and some have RW. The R stands for readable, while the W stands for writable. Then what are the differences between them? The DVD-R/RW standard was developed by Pioneer, and is used primarily by Apple and Pioneer. The "minus" discs can only be written to in one layer on the disc surface. This format is supported by the DVD forum but is not an industry standard. So they are cheaper than the "+quot; format. The DVD+R/RW format is supported by Philips, Dell, Sony, HP, and Microsoft. These discs can be written to in multiple layers, having slightly better and more disc storage than the "minus" format. And of course, they are expensive than the "minus" format. About the plus side, DVD+RW came before DVD+R. The plus formats have the same data storage capacity as the minus formats, but DVD+RW offers faster writing, better internal linking and supports for drag-and-drop desktop files.
In general, the main difference between DVD+/-R (DVDr) and DVD+/-RW (DVDrw) is that the R is a write-once format. Data can be burned on the DVD only once. An RW disc can be erased and rewritten hundreds of times.
