Formatting

Anyone notice how all the [edit] links are grouped at the See Also section? Anyone who knows how to fix this, can you do so?

Looks like a style sheet issue because of the floating images at right.

Relevant imagery

I think we could provide some much more relevant images for this article, diagrams on how the technology worked would be far more appropriate, and we do not need an image to describe what a spindle is Protiek 12:28, 24 May 2006 (UTC)

Playability life

I think a very valuable addition to this discussion would be how long playability life is. I have heard that it's around 5 years before burning and around 30 years after burning, but I have no source and no idea about it's reliability. Anyone who would know, thanks!

so, which is better? dvd-r or dvd+r? Jm51 02:25, 1 Jan 2005 (UTC)

How about some info on dye colors and/or a picture of a DVD-R? SamB 14:33, 20 Jan 2005 (UTC)

Actually, MSN has released an article that said that the life of a burned or pressed CD or DVD is, at maximum, for 4 or 5 years, even if you store it in a vault. Of couse that this is very relative. Some media may endure for 10 or 15 years.

--Emperor Richard 23:01, 3 July 2006 (UTC)

4-5 years seems absurdly short based on real-life experience. I have playable CDs that are 15+ years old, and playable DVDs that are 7+ years old. These are discs that have been regularly used, and for most of that time I've been without air-conditioning so they've been exposed to temperature and humidity fluctuations. Can anyone provide a citation for playability life? Cmadler (talk) 16:55, 11 December 2008 (UTC)

It may be that they are refering to what is known as the 'archival life'. This is the time period for which you can guarantee to recover all the data from a single archived copy of the medium. It is the minimum life and is considerably shorter than the average life. Many people do not realise that the archival life of paper documents (made with modern paper) is just 10 years even though, on average, they may last several decades. 109.153.242.10 (talk) 13:00, 30 December 2011 (UTC)

+ and - actual difference

I have been trawling the net for a long time now looking for the physical diference between a DVD-R and a DVD+R. There are plenty of threads telling of how they are two competing standards and that they are two competing formats etc, but no information (that I can find) on the defining difference between the two that means that a DVD-R cannot necessarily be played in a DVD+R machine and vice versa

A very interesting article that claims the superiority of DVD+R over DVD-R: Why DVD+R(W) is superior to DVD-R(W) - Michael Spath

The diference between a DVD+R and a DVD-R is how it is read. DVD+R are read by reading the pitch frequency of a disk. A DVD-R is read by reading the wobble distance between 2 points. DVD+R are a bit cheaper and are more supported by DVD readers.

--Emperor Richard 23:01, 3 July 2006 (UTC)

There is no difference in the way they are read. The difference only affects the way in which they are writen to. 109.153.242.10 (talk) 16:08, 31 December 2011 (UTC)

Capacity

Does anyone know the exact capacity of a DVD–R in bytes? —Typhlosion 00:11, 29 November 2005 (UTC)

DVD-R is rubbish, cyclic redundcy check errors are ENORMOUS, do not buy them , buy DVD+R or just buy a hard drive

Please note: "Article talk pages should not be used by editors as platforms for their personal views." 152.130.12.64 (talk) 22:18, 8 May 2009 (UTC)

dvd+r's are also known to have 313 errors but yes overall dvd+r's are a better choice

The capacity of DVD-R are equal as the capacity of a correspondent DVD+R.

(Please sign your posts by typing four tildes)

No they aren't.

DVD-R SL 2,298,496 bytes.

DVD+R SL 2,295,104 bytes.

DVD-R DL 4,171,712 bytes.

DVD+R DL 4,173,824 bytes.

75.84.238.18 (talk) 09:28, 30 November 2009 (UTC)

These are remarkably small DVDs that you talk about. Single layer media is nominally 4.7GB and Dual layer, 8.5GB. Nowhere near the figures that you provide. You figures don't even match the 8cm discs. 109.153.242.10 (talk) 16:11, 31 December 2011 (UTC)

I was going to add a handy column for GiB, but when I click edit I can't see the table, only a tag that says "{ { DVD capacities } }". The data for the GiB column in order from top to bottom would be: 4.38, 4.37, 7.95, 7.96 with the header linking to "GiB". How does one edit the actual DVD capacities table? 118.208.126.106 (talk) 07:53, 21 April 2012 (UTC)

If you do so then please use Gigabytes not Gibibytes. Wikipedia policy is not to use the later (see WP:MOSNUM). 86.169.33.6 (talk) 14:43, 22 May 2012 (UTC)

R v. RW

So, since it is not REwritable, does that mean I can't reFORMAT it? Is rewriting and reformating the same thing (different names), similar (different things), or completely dfferent?

---

Not entirely. Nero can perform an operation that permits to "rewrite" a DVD+R or DVD+RW. DVD+RW may be written several times over (about 1000) but it is done in a different way. The only difference is that, in a DVD+R, the data remains the same (it is "invulnerable"). In a DVD+RW, data is not as invulnerable as in a DVD+R, because it can still be written over and over again.

--Emperor Richard 23:01, 3 July 2006 (UTC)

Dash and Minus

I've heard a few people using "minus" instead of dash, so this might not be incorrect, just another variation. --Evilboy 09:56, 22 April 2006 (UTC)

That would make sense too since you would have to say "plus" for DVD+R.

---

Actually, it's the only thing that makes sense. One is "plus", the other one "minus", even if it is historically stupid to playback, the errors on the format where so great I destroyed the disc and started useing the Plus format. DVD-R is incredibly inferior to DVD+R (the same with rewritable) so if any one wants this up for "discussion" with me go ahead. (I was annoyed yesterday to find that Panasonic, Sansung and a cheap make called Funai only use the - format in their recorders, but one sony model uses plus, and it dosen't matter beecause noone buys Funai, Samsung are stupid and Panasonic does put DVD-RAM in their machines.)J2F Duck (talk) 11:20, 5 March 2008 (UTC)

J2F Duck, the Talk Page Guidelines state "Article talk pages should not be used by editors as platforms for their personal views." 152.130.12.64 (talk) 22:19, 8 May 2009 (UTC)

To be strictly accurate, it is a dash (or hyphen) not a minus. This comes about in the same way as the recordable CD is CD(dash)R. The plus was adopted to indicate a recordable DVD-RW that had some extra technology (i.e. plus something) that allowed for more accurate repeat writing. That users refer to the DVD-R as DVD(minus)R is probably understandable. 109.153.242.10 (talk) 16:42, 31 December 2011 (UTC)

Dyes

What type of dye is used in DVD-R? 65.188.253.13 03:33, 26 January 2007 (UTC)

I want to burn my own dvds

What format should I use? I want to burn my own dvds to play on regular dvd players. Family Guy Guy 01:23, 4 October 2007 (UTC)

Use any media that's compatible with your DVD Player. If in doubt use DVD-R but I personally prefer DVD+R and my player (and most of my friends and family's players) play +R without issues but once in a while you may come across some older or really cheap players that won't read +R smoothly.Payam81 (talk) 06:34, 30 December 2007 (UTC)

if u have a 1998 dvd player dvd+r almost certainly won't work, if it's after 2002 it's almost certain +r will work. but when you're not sure DVD-R is a safer bet Markthemac (talk) 06:41, 27 January 2009 (UTC)

Fix the bold text

Somebody please fix the bold DVD+R hype in the article. --Xerces8 (talk) 08:18, 12 February 2008 (UTC)

Plus/minus comparison

Please remove the +/- piss contest and make and link to a factual +/- comparison page. --Xerces8 (talk) 08:18, 12 February 2008 (UTC)

Restructuring

If you compare this page to the DVD+R page, the styles do not match. Jaypvip (talk) 10:22, 28 February 2009 (UTC)

Sizes?

Why are gigabytes used in the size comparison chart instead of gibibytes? What is useful about simply dividing the number by 1000000000? Can't readers do this by themselves without our help? 76.240.195.199 (talk) 01:30, 27 April 2011 (UTC)

Because Wikipedia discourages the use of gibibytes, (See WP:MOSNUM) 109.145.22.224 (talk) 16:01, 20 April 2012 (UTC)

What a beautiful capacity table. But who the heck had the idea of building the capacity table with Bytes | Mibibytes | Gigabytes?? Was it too hard to do Bytes | Megabytes | Gigabytes? Or worst case do it with Mibibytes | Gigibytes? Because otherwise people get all confused reading the table :S Just saying... — Preceding unsigned comment added by Rds correia (talk • contribs) 21:19, 17 September 2014 (UTC)

References(gasp)

.. to blogs!! Oh noes 1!!eleventy-one

Fact is, these sources are quite good. Another example of why blogs shouldn't be tarbrushed as unreliable sources.

There's a few decent pages from trade sites etc with more detail on the underlying technology differences between +/-, I'll try and update the family of DVD format articles with some derivations and ref them..

I know it's naughty but I've noted some here for self-reference: http://www.myce.com/article/Why-DVDRW-is-superior-to-DVD-RW-203/ http://www.dvddemystified.com/dvdfaq.html#4.3 http://www.cd-info.com/dvd/dvd-plus-r-dl/index.html http://www.supermediastore.com/article/u/how-to-burn-dual-double-layer-dvd-media http://www.myce.com/article/Why-DVDRW-is-superior-to-DVD-RW-203/ http://www.cd-info.com/dvd/dvd-plus-r-dl/dl.html benryanau 06:13, 21 January 2012 (UTC)

Good or not, blogs are self published sources seldom backed by a reputable source and often may be Original Research. These are unacceptable as reliable and verifiable references. 109.145.22.224 (talk) 16:04, 20 April 2012 (UTC)
