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.
The R format DVDs can be written once and read arbitrarily many times. Thus, R format discs are suited to applications such as non-volatile data storage, audio, or video. This can cause confusion because the DVD+RW Alliance logo is a stylized 'RW'. Thus, a DVD+R disc may have the RW logo, but it is not rewritable. According to Pioneer, DVD-RW discs may be written to about 1,000 times before needing replacement.
