DVD-RAMA rewritable DVD disc endorsed by the DVD Forum. Using phase change technology, DVD-RAMs are like removable hard disks, and the media can be rewritten 100,000 times compared to 1,000 times for DVD-RW and DVD+RW. The first DVD-RAM drives with a capacity of 2.6GB (single sided) or 5.2GB (double sided) became available in the spring of 1998. DVD-RAM Version 2 discs with 4.7GB arrived in late 1999, and double-sided 9.4GB discs in 2000. DVD-RAM drives typically read DVD-Video, DVD-ROM and all types of CD media. See DVD, DVD storage capacities, DVD+RW, DVD-RW and optical disc.
