Like DVD-R, DVD-RAM is a format for creating your own DVD video discs. However, unlike DVD-R, it's a rewritable format — DVD-RAM discs can be erased and re-recorded up to 100,000 times! DVD-RAM recorders feature a very high data transfer rate (22.16 Mbps), and employ random access storage and retrieval, like a computer's hard disk drive. This method of handling data gives DVD-RAM some handy capabilities that you don't get with other recordable DVD formats. For instance, some DVD-RAM decks give you simultaneous, independent playback and recording — you can watch one recorded program while a different one records, or watch a program from the beginning while a later portion of the same program continues recording. Once you've recorded a series of scenes or programs onto a DVD-RAM disc, you can rearrange the playback order, or remove unwanted segments altogether. However, there's a bit of a trade-off for the added flexibility: DVD-RAM discs are not compatible with most regular DVD players and DVD-ROM drives. (So, for instance, if you want to record home movies to a DVD disc that you can send to a family member or friend, consider using the more widely compatible DVD-R format.)
