Just wondering if DVD-RW works the same as a DVD+R when it comes to recording? I want to know if I can use a DVD-RW to re-record over and over instead of using the regular DVD's, burn once and they are done.
How many times can U re-burn over a DVD-RW?
Do DVD-RW's work in a Dvd player that currently can play DVD+R?
DVD-RW do not play in all set top's, I have no trouble with +R but -RW won't play on the TV, fine on the pc. Don't quote me on this but thought I read year's ago that an RW could be recorded over about 1000 time's, I can attest to at least a few hundred time's so far. Don't know but maybe depend's on quality, I only use Verbatim RW.
DVD-RW media are made to the same DVD Forum specifications as DVD-R. (DVD+R is not endorsed by the DVD Forum.) The erase cycle is supposed to be 1,000 times, but very many begin to show increasing jitter beyond 600 write/erase cycles. The semi-metal alloy used in rewritable media begins to break down around 1,000 (or 600) cycles. RAM discs use thermal dielectric layers and multiple layers of alloys to allow many more write/erase cycles, but that manufacturing process is lot more expensive.
The reflectivity of rewritable discs is lower than that of dye-based discs, but that should not pose a problem in modern DVD players.
600-1,000 erase cycles. That's not "unlimited," even generally speaking. Rewritable media have slower write speeds because of the physical/chemical limitations of the recording alloys: their range of reaction to heat pulses is much more limited than that of recording dyes. A modern CD-R dye has a range of about 8X to 52X. A CD-RW with an 8X range has an upper limit of about 16X. If DVD-RW or DVD+RW move to 8X, they can no longer work at 1X, which means they no longer work as substitutes for VHS tape in time-shifting video recorders. That is the major reason why most remain 1X to 4X.
DVD+RW is far superior to DVD-RW in terms of recording flexibility, speed of formatting, and speed of erasure. DVD-RW is merely an "erasable DVD-R," a design meant for sequential video recording. DVD+RW was designed from the start as a video and data medium.
