What’s the difference between the plus and minus?
In order to
explain this we must take a trip back in time. When DVDs were first
being developed, there was no industry standard. Multiple companies
were competing to develop what they hoped would be the dominant form of
the future.
The DVD-R DVD+R difference can easily be summarized by the following:
- The
DVD-R/RW standard was developed by Pioneer, and is used primarily by
Apple and Pioneer. These “minus“ discs can only be written to in one
layer on the discs surface. In addition, this format is supported by
the DVD forum, but is in no way an industry standard. DVD-R/RW discs
are cheaper than the “plus” format. - The DVD+R/RW format
is supported by Philips, Dell, Sony, HP, and Microsoft. These discs can
be written to in multiple layers, giving them slightly better and more
disc storage than the “minus“ format. Because of this additional
capacity, they are slightly more expensive than “minus“ discs.
