Using Seasons for Dates[edit]

Should northern hemisphere seasons be used to date something? "Summer 2003" should probably just be "mid-2004", if a specific month can't be agreed upon.

I think it's understood that "Summer 2004" means northern hemisphere summer if it is not otherwise specified. Most if not all of the firms developing this technology are northern hemisphere, and the northern hemisphere contains most of the world's land and population.
NO!
I'm confused...why would "Summer 2003" equal "mid-2004"? Wouldn't it be mid-2003, or perhaps late 2003? Was that a typo or are you getting at something that I'm just not understanding? I agree that if there isn't anything important about the season (i.e. we're not talking about the Summer Olympic Games, or the Winter pre-holiday buying rush) that something non-regional should be used to refer to a date that doesn't tie it to a particular area of the planet. --Kadin2048 21:10, 10 July 2006 (UTC)[reply]
Why not change it to Financial Quarters ie Q2/3 2004 or something similar. There is no real need to say "Summer 2004" unless it is specific to the region. --Weyoun6 00:43, 5 Apr 2005 (UTC)
Or some reason the fact that it's summer is relevent, which would be rare when talking about computer storage technology. See Wikipedia:Manual of style (dates and numbers)#Seasons. - dcljr (talk) 00:07, 28 May 2006 (UTC)[reply]

Capacity[edit]

Does anyone know the exact capacity in bytes of a DVD+R DL? —Typhlosion 00:12, 29 November 2005 (UTC)[reply]

According to this page [1] Blank Disc Capacity : 4,171,712 Sectors = 8,147.9MB = 7.96GB (8.54GB); so really it's 7.96 GiB ("real" gigabytes) and 8.54 GB ("marketing dept" gigabytes). It makes little sense to express the capacity in bytes since the sectors are bigger than bytes. --Kadin2048 20:18, 10 July 2006 (UTC)[reply]

Red bar usage[edit]

Does anyone else think the bar should be changed to bold from the red background? Red is way to harsh for a list to simply indicate where in the list the current article is. Just a thought. Chotchki 14:13, 15 September 2007 (UTC)[reply]

I agree--58.84.139.52 08:41, 1 December 2007 (UTC)[reply]
Agreed! I will act on replacing the red with a more neutral gray tone on all the related articles.Payam81 (talk) 00:19, 2 January 2008 (UTC)[reply]

Double versus Dual[edit]

I think the intro should be cleaned up as to what DL stands for. It sounds like some ignorant person just assumed they could state their beliefs on the matter. The fact is that most of the companies use the term Double Layer including Mitsubishi (which was one of the DVD developing companies) Ltsgosrfn 16:13, 23 November 2007 (UTC)[reply]

Here's one to make it even worse, the DVD+RW Alliance (the official industry group in charge of all things "DVD plus",) calls their two-layer system "Double Layer". It's the DVD Forum (the official industry group in charge of all things "DVD dash",) that call their two-layer system "Dual Layer".
I'm changing the page. It's official, from the industry organization in charge, "DVD+R DL" stands for "Double Layer", whereas "DVD-R DL" stands for "Dual Layer".
(For more useless information, the "DVD Forum" is the standards body that covers DVD Video, DVD-ROM, DVD-RAM, DVD-R, DVD-RW, DVD-R DL, HD DVD, HD DVD-R, and HD DVD-RW. the "DVD+RW Alliance" covers only DVD+RW, DVD+R, and DVD+R DL. And the "Blu-ray Disc Association" covers everything Blu-ray.) Ehurtley (talk) 07:27, 24 November 2007 (UTC)[reply]

Thanks for that. I hope I didn't offend (and I didn't mean to) when I said ignorant in my previous post. I am also ignorant of many things in this world!Ltsgosrfn 13:55, 28 November 2007 (UTC) —Preceding unsigned comment added by 59.147.118.157 (talk) [reply]

But to be fair, DVD-RAM is pretty much a dead format, HD DVD, HD DVD-R and HD DVD-RW are most probably going to loose the format was against Blu-Ray Disc, DVD-R DL is not a widespread format (and not greatly sucsessful), leaving the only widespread formats with a good looking future under the DVD Forum, DVD-ROM, DVD Video, DVD-R and DVD-RW. (DVD Forum also covers HD DVD-RAM and DVD-RW DL but both of them also look dead), so my point is that the only DVD Forum controlled formats with a future are DVD Video, DVD-ROM, DVD-R and DVD-RW (though the last two are starting to become a bit shakey against the plus formats). —Preceding unsigned comment added by J2F Duck (talk • contribs) 22:10, 13 February 2008 (UTC)[reply]

Minus R Dual Layer V Plus R Double Layer[edit]

If anyone goes around and has alook at catalouges, internet shops or high street shop, it is very rare to find a Minus R Dual Layer, some of this I belive is down to compatability problems with the format, I have also met quite a few computers with DVD writers on bearing the DVD-R Dual Layer logo on, what is the point of this if you cannot buy the discs to work with them. Meanwhile it is not uncommon to find their Plus cousins (+R Double Layer) so this suggests that Minus R Dual layer is like Betamax. J2F Duck (talk) 16:25, 9 March 2008 (UTC)[reply]

all +R dual layers burners today can also burn -R, there is no competition between plus and minus today so it's not anything Markthemac (talk) 00:43, 20 July 2009 (UTC)[reply]


I suggest deleting this article and redirecting this page to DL section of the main DVD article. If in this article are informations not contained in DL section of DVD article, it will be good to move them there.

What is IS media?[edit]

On some of the disc burning forums I've seen mentions of IS media and that it tends to be incompatible with some older DL burners. I've run into this myself with some Memorex 8x DVD+R DL media that my laptop refuses to read and will automatically eject blank ones. I can burn them with other drives and they'll read in them too. Since web search engines are all simultaneously too stupid and attempting to out-think the user, it's impossible to find out anything about this. The Web needs a search engine that is case sensitive and *really dumb* so it will only look for EXACTLY what the user enters. Bizzybody (talk) 08:17, 9 November 2011 (UTC)[reply]

Could you provide some context. I can't find any on line reference to 'IS media'. 86.147.237.233 (talk) 12:13, 1 April 2012 (UTC)[reply]
