DVD-R is an RW?

[darkflux]

this isn't necessarily a DVD Ripping Question, i just figured i'd get the best response from fellow rippers. feel free to move this as necessary.

so i've noticed that some DVD-R brands (mostly Maxell and Memorex), over the past couple years, have started putting "RW" on the packaging and discs as well, and as i have not yet seen a thread about this, thought i would inquire into the community. what i'm talking about is this:

notice how, directly over the DVD+R it says RW. i have yet to hear this talked about, and am not sure if this is some sort of specification or something, or what it is called, but it is appearing on many discs in all brands:

and EVEN ON VERBATIM DISCS!:

can somebody please tell me what this means, and why it only appears on DVD discs, and primarily on DVD+R or DVD-R, and less frequently on the DVD-RW and DVD+RW discs?

i just know i am totally going to feel retarded when i find out it's something simple, it just bugs me, and i get people calling me all the time saying "My RW disc won't erase!" when it's NOT a DVD-RW disc, just a DVD-R with the letters RW promionently displayed, and it just stresses me out trying to explain it when even i don't fully understand it!

sorry, done ranting now...

But it shouldn't be on any DVD-Rs though.

[jman98]

For those not interested in following the link, it's the logo of the DVD+RW alliance. It should only appear on + media as Baldrick says. It has confused many consumers. As far as I can tell in the past it was displayed in very small letters and it's only been a recent decision to display it in large letters and thus confuse many people.

[SWBisbee]

Take another look at all your labels I'm almost sure one of them says "Write Once" on one of the labels, if it does not it is understood it can only write once, with write once you can not erase.

Perhaps I am having a blonde moment but I could not see any dvd -R disks in the links you posted ?????????

I think the DVD Alliance had a "Blonde Moment" when they picked the logo....

[darkflux]

yeah, as Baldrick noted, the DAEWOO discs had them too, but maybe they were just as confused as i was

so yeah, THAT'S MADNESS! but yeah, it makes more sense now. they should've picked another Logo, i think, or at least opted out of having it posted on the discs.

...so then, what was the "Alliance" for CD-Rs called, or was there one?

[AlanHK]

While we're at it, WTF does the "RW" stand for then? I Googled it and couldn't find any explanation.

Surely not "Read-Write?

[darkflux]

heh, good question AlanHK. even their website doesn't mention anything of it:
http://www.dvdservices.org

the Wikipedia pages don't either, and don't even have the logos!:
http://en.wikipedia.org/wiki/DVD%2BRW_Alliance
http://en.wikipedia.org/wiki/DVD_Forum

...does anyone else find it interesting that these two groups' founding members are a lot of the same companies? kinda like CocaCola and Pepsi, right?

"No, Pepsi sucks! Drink Coke!"

[DB83]

Maybe we should run a comp for the most apt name ?

How about 'Rival Works' for a start.

Well atleast we know what VHS stood for - Very High Standard

[darkflux]

how 'bout "Rarely Works"

that's been my experience

The DVD forum site has a section that states:


DVD-RW
Similar to DVD-RAM except that its technology features a sequential read-write access more like a phonograph than a hard disk. Its read-write capacity is 4.7 Gbytes per side. It can be re-written up to about 1,000 times.

yes, but that is NOT the DVD+RW Alliance, that is the DVD Forum, which is their "competitors". and i'll bet you ANYTHING the DVD+RW Alliance has similar statements on their site. the point being, why choose "RW" for your logo, when BOTH formats are "Read-Write"?

[lingyi]

RW = ReWritable

I know...not the most intuative answer, but a logical carryover from CDRWs which are also ReWritable

Here's a link to a white paper from the DVD Alliiance site. Note the logo on the top left of the first page.

[mrswla]

linqyi, have you read any of the previous posts? There is no way RW stands for ReWritable when it is on DVD+R and DVD-R write once discs!



If it were ReWritable, then I think the DVD disc makers would have a class action lawsuit on their hands for false advertisement!

[usually_quiet]

The abbreviation "RW" always stands for "rewritable" when referring to optical media formats.

Apparently, one of the goals for the DVD+RW Alliance, which was resonsible for developing all the "plus" formats, was to create a new kind of rewritable media. Once they decided on using "RW" in the name for the group, it isn't hard to understand how they might pick "RW" for their logo, although they apparently didn't think about the confusion that might cause for the public.

If it is on a -R or +R (i.e without the W) then it obviously stands for 'Rite Wonce' (just say it after a hot curry or with a mouthful of rice)

I think we figure it out!!
