Different types of DVDs?

Question

What is the difference between DVD-RW and DVD+RW?

Answer 1

RW are Read Write disks

Most people think - and + are the same, but there are two issues

1. compatibility - some players will play one or the other but not both - however - some players won't play RW disks at all. Today, most play all.

2. + disks actually have a lower error rate than - disks because of the way they are recorded. The data has less jitter so it is less error prone. Bottom line, it is hard to tell the difference.
