A DVD-RW disc is a rewritable optical disc with equal storage capacity to a DVD-R, typically 4.7 GB. The primary advantage of DVD-RW over DVD-R is the ability to erase and rewrite to a DVD-RW disc.
Branded Top Surfaces mean that these discs have surfaces with some sort of markings on them. Typically the manufacturer’s logo, disc speed, type of disc and lines to write in a description.
