Early DVD-RAM discs required an enclosing cartridge, which meant they would not fit in most DVD players or DVD-ROM drives. Therefore, you would need a DVD-RAM drive to use DVD-RAM discs, as well as burn them. Newer DVD-RAM discs, however, can be used without a cartridge. These discs can be played in any DVD player that supports the DVD-RAM format. While the first DVD-RAM media could only hold 2.6GB on a single-sided disc, newer double-sided discs can store up to 9.4GB.
