i was just woundering what the deal with these DVD-RAM Discs i keep coming across in stores when i pick up dvd recordables i was just woundering what they are.
Quote:Compared with other writeable DVDs, DVD-RAM is more closely related to hard disk technology, as it has concentric tracks instead of one long spiral track. Unlike the competing formats DVD+R, DVD-R, DVD+RW and DVD-RW, special DVD burning software is not required to write or read DVD-RAMs on a computer. DVD-RAMs can be accessed like a usual floppy disk or hard drive.
Of course, you have to have a DVD-RAM drive to use them.

CoreBus- And in addition too what waynekusa said about DVD- Ram unless it's Used in its case/cartridge it's just as susceptable if not moreso to scratches and damage to the recording layer/read surface! Some Reacorders are designed to take the DVD-Ram cartridge But From what I understand most Burners that are DvD-Ram Capable do not! I'm not knocking it as a format but ! not having the capability to use it & with the low low prices for quality Dvd media at this time I see no need to invest in another format at this time ! Also although DVD-RAM is available at many retail locations - DVD+R, DVD-R, DVD+RW and DVD-RW, are still somewhat more Ubiquitous " available nearly everywhere" another point to consider . Good luck CoreBus and happy Burning !
DVD-RAM is a rewritable format approved by the DVD Forum for data recording. DVD-R was supposed to be for video, but people insisted on Pioneer's developing a cartridge-free rewritable format using the DVD-R system. Philips, Sony, and HP thought that a video format compromised to do data was idiotic; so they split from the DVD Forum and developed the DVD+RW for both video and data. People insisted on a write-once version of that; so DVD+R finally came out.
DVD-RAM uses multiple layers of phase change material and dielectric layers that act as thermal blankets for the discs. That allows them to be erased and re-recorded 100,000 time rather than 1,000 times as in the DVD-RW and +RW. The address format is molded into the substrate of the DVD-RAM disc--that's the pattern you can see on the bottom. The original cartridge was supposed to offer extra security for data, but users wanted the bare disc and finally got it. The bare disc is no more susceptible to scratches or other problems than any other DVD disc.
