DVD+RW

DVD+RW is the name of a standard for optical discs: one of several types of DVD, which hold up to about 4.7 GB per disc and are used for storing films, music or other data.

DVD+RW supports random write access, which means that data can be added and removed without erasing the whole disc and starting over (up to about 1000 times). With suitable support from the operating system, DVD+RW media can thus be treated like a large floppy disk.
