Do you really want the technical differences?

Non technical differences:
Essentially they are - and + to be competing record once versions for "R" and rewritable many times for the "RW" Originally, the + was said to be best for data and the - for media but as time progressed they have been found to work equally well. As a DVD duplicator we choose the - version for greater compatibility with older players. The RW versions will be slightly higher price and are purported to have a reduced life span for permanent storage. But, they offer a disk that can be reused many times which would be good for something like a backup disk set for data that changes every so often. If planning for shelf life more than 10 years, it is recommended you burn the "R" version.
