Methods used against bad breath, such as mints, mouth sprays, mouthwash or gum, only temporarily mask the odors created by the bacteria on the tongue, but cannot cure bad breath because they do not remove the source of the bad breath.
A DVD-R is a write-once format: once youâve burned the data onto that DVD platter, the disk is forever frozen with that information. Add the âWâ to that, and youâll find that DVD-RW can be erased or rewritten up to a thousand times.
Take note of the fact that there are two variations of a DVD-RW drive. The first variation is DVD-RW (notice the - sign). The second variation is DVD+RW (notice the + sign). A DVD-RW drive can only burn DVDs to a depth of one layer. A DVD+RW drive can burn DVDs to a depth of 2 layers, or dual layer.
