A rewritable (ie. recorded material can be erased or over-written) recordable DVD. This format is supported by the DVD Forum. It should noted that DVD-RAM has very limited compatibility with standard DVD players (although recent Panasonic models support it), because it uses significantly different technology to the other types of recordable DVDs. In particular, it offers true random access writing to identified sections of the disc, which has allowed Panasonic DVD recorders to implement a 'time-slip' feature (continuous recording, and the ability to rewind and watch recorded material, even while recording continues). It is also said to support a higher order of magnitude of re-write cycles than either DVD-RW or DVD+RW.
