DVD+RW Question

[muthabored]

How often can you write to a new/blank DVD+RW before it can no longer be written to or is there a limit? Does writing to a DVD+RW multiple times degrade the quality of the media or is there something else that renders it unwriteable after so many times?

DVD-RW has a similar re-write tolerance as a CD-RW, able to be erased and rewritten to about an average of 1000 times. Quality doesn't change, although the physical condition of the disk degrades a very small amount per re-write (though not enough to notice).

DVD-RAM, I believe, is the one type of media that stands out from the crowd. I've heard claims as high as 100,000, though a figure like 25,000 is probably a better estimate.

There is no noticable change in quality upto at least 600 times. I think you should safely be able to rewrite at least 1000 times or more. Technically speaking, each time you write, the recording layer of the disc gets thinner and thinner until there comes a time when it wears out completely. Each write operation would thus progressively degrade the quality of the recording.
If you can afford it, try DVD-RAM.

Well, data is recorded in digital format. If a file is written on a disk that has been rewritten 100 times, the file either works or doesn't work. Same goes for audio files. It either plays or doesn't play. The quality doesn't change. At some point, the "physical condition" (recording layer) wears down to the point where pieces of the file (bits) do not write properly and the file is corrupted.

Quality isn't technically an issue here. Wookie, you pretty much restated everything else...

Thanks to the both of you.
