Digital Versatile Disk Random Access Memory
<storage> (DVD-RAM) Rewritable DVD media that is recordable on both
sides, giving up to 9.6GB of storage. A drive can record to disk and read from
it at the same time, so the term full duplex is often used. There are two
general types of media: traditional discrete disk in DVD or Jewel case, and one
in a permanent case like a large floppy; the disk remains in the case, and the
case goes into the drive. The former can sometimes be read by regular DVD
drives; the latter obviously cannot.
