Of course, they still may keep a hold on the consumer video market...their size is ok for that, while HVDs will be more expensive, but absolutely vital for the IT industry. Grendelum 03:24, 26 February 2007 (UTC)
- Q When will HVD products be generally available?
- A HVD drive and disc designed for enterprise market will be available starting summer 2006.

Do you think the disks will be used for say the Ultra High Definition Video standard? 159753 11:45, 15 July 2005 (UTC)
Yeah it can hold 11 hours of compressed Ultra High Definition Video (The 3.9 terabytes version) Uber555 02:06, 27 March 2007 (UTC)
Well, a 3.5 hour movie would be around 900 gigs with audio (both compressed). Assuming that 1.6 terabyte discs become reality (or the 3.9 ones), that would easily be enough space for LotR: tRotK + extras. And that's about the longest movie I ever intend to sit through:P.

I don't see holographic discs as a mass-distribution medium. CDs, DVDs, HD-DVDs and the like are injection-moulded. One machine can produce hundreds of DVDs per hour, for pennies apiece. Holographic discs (I think) would have to be written one at a time. You can't distribute a game or a movie that way. Spiel496 18:22, 30 May 2006 (UTC)
Yes, but they say the price will drop. Uber555 02:09, 27 March 2007 (UTC)

This article seems a bit biased. If these have such huge capacity and such fast write-speed, why aren't they common? Is it just price, or are there still some problems in need of fixing before these become mainstream? NPOV, people, not just the info in the companies' advertisements. Twilight Realm 00:09, 27 September 2005 (UTC) Probably because it's still in the research phase.

Not so, you merely need to identify a strategy for one player that inevitably leads to a win within a finite number of moves. This is likely to be vastly smaller than the set of all possible moves. Stub Mandrel ( talk) 17:09, 19 January 2016 (UTC)

Is gigabyte the right term? giga refers to the decimial system while Gibi refers to binary. So Would that make the correct term Gibibyte?
Gigabyte is the common term at this time, regardless of technicalities. My guess is that "this is an encyclopedia for the masses, not a technical journal" applies.
I changed some of the parts about InPhase's competing media, and removed an erroneous part about InPhase releasing a HVD disc in 2006. Seeing as InPhase is working on an entirely separate standard, maybe it should get it's own article, or maybe this article should be renamed to include all holographic standards?
Stabilizing Ferroelectric Materials
I removed the following sentence:
It's rather poorly written. Firstly CD-Rs use infrared lasers. Secondly, it's not clear to me what it's talking about. Is it talking about the power of the laser used for reading or for writing? If it's for reading, we should be talking about the laser in CD-ROM and DVD-ROM drives. Of course, CD-RW drives and DVD+/-RW drives also have a laser but AFAIK the laser is higher power and the high power is needed/used for writing (when reading it uses less power). If it's for writing, then we should refer to them as CD-RW and DVD+/-RW drives or something like that since that's what they're commonly referred to as and make sure we're clear it's for writing. Regardless, is the 1w green laser currently the laser power needed for HVD for reading or for writing? Clearly we should be comparing apples to apples so the laser power should be either reading or writing (or both) for both. Also, I'm guessing BluRay and HD-DVD blue laser power is probably similar but we need to be clear. Nil Einne 12:09, 26 May 2006 (UTC)

I changed the piece about the standards, reflecting the changes and the final approval of the Ecma standards.
Also, the HVD Alliance website is emptied, it's all moved to HVD FORUM. Changed that too.
It says this early in the article:
"The HVD also has a transfer rate of 1 gigabit/s (125 megabytes/s)."
However, in the Storage capacity in context section, it reads:
"The transfer rate is at an average of 1 gigabyte/second, or 1024 megabytes/second, around 380 times the transfer rate for current 16x DVD storage."
Can someone can clarify which one it actually is?

Look who was wrong 4 years ago. In the meantime, HDTV adoption has become widespread, and Blu Ray, which has become the only physical media for 1080p video offers hi-def 3D at a superior quality over streaming (the infrastructure just isn't there and people also still like to physically own things they pay for). Unsurprisingly, Blu Ray now has a 25% share of the home video market, 40% of the sales of newly released movies go towards Blu Rays. The price of 50GB BD-Rs has come down to ~$3.60 USD per disc. That means, for Blu Ray the price per Gigabyte now is $0.078 USD, whereas the price per Gigabyte for DVD-R now is $0.069 USD - a negligible difference. The price for PC Blu Ray writers is below $100 USD. At the time of this writing, Blu Ray is the only media for long term storage of large amounts of data (eg. hi-res video and images). Properly stored, BD-Rs are expected to last at least 30 years, possibly 100; no HDD lasts that long. At present, there is really no alternative. While I have no doubt that HVD would be a good format, don't expect it to be introduced any time soon. None of the companies that backed Blu Ray have even the slightest interest (or reason) to make another switch for the next couple of years. Until Ultra HD becomes the norm (which could take until 2020 or longer), there won't be much demand for a larger physical format, and even then Blu Ray might still be enough: "On July 20, 2010, the research team of Sony and Japanese Tohoku University announced the joint development of a blue-violet laser, which will help in creating Blu-ray discs with a capacity of 1 TB (dual layer)." The next generation of video game consoles (Wii U, PS4, Xbox 3) will all feature a Blu Ray based storage format. In summary: Go ahead and buy a BD drive for your PC. Blu Ray won't be obsolete any time soon. — Preceding unsigned comment added by 93.193.185.64 ( talk) 15:16, 17 September 2012 (UTC)
>"Generally you're looking at a lifetime of less than 10 years." That is not true. I have talked about this with several experts; for instance Verbatim (Mistubishi Chemical) confirmed that they expect writable HTL BD media (inorganic dye) to last 30 years or more. I own several Verbatim Azo dye CD-Rs written as early as 1995 (=17 years ago), they were stored properly and still work perfectly. Note that Azo dye is organic, and thus much more light sensitive than HTL BD-Rs; so there is no reason to assume that BD-Rs won't outlast CD-Rs. Of course if you buy cheap no-name discs, then you get what you pay for. Hdds certainly are more convenient (speed-wise) than optical discs, but to really be on the safe side you need to migrate your data to new drives every 5 years and keep multiple copies, which makes the price per GB much higher than using BD-Rs. — Preceding unsigned comment added by 93.193.180.202 ( talk) 04:44, 30 October 2012 (UTC)

In the first paragraph, the disk is described as having data read by a green laser, while tracking is done by a blue laser. In the second paragraph, however, we are talking about green for data and red for tracking. My question is this: RED OR BLUE? I know it's a simple find & replace job, but I don't know enough to determine which colour is correct. 118.208.105.69 ( talk) 03:55, 24 January 2010 (UTC)
This is all very interesting to me i'm just waitiing for this technology to actually become a reality, but the answer to your question is that the red laser is used to read the data in a normal cd/dvd medium however with blu-ray it uses blue laser hence why its called blu-ray

"ge has had holographic storage disks since 2009 capable of being played with curent blueray systems, this artical needs to be fixed. disk player costs should be ~$120-500 and discs should be <$50 (cheaper than bluerays to produce and record)" —Preceding unsigned comment added by 117.120.16.131 ( talk) 06:20, 2 May 2011 (UTC)
Among other things, the article lede claimed planned release dates of 2019 and 2020, without references. It's unlikely that any technology company would announce a release date so far in the future. Using WikiBlame I found that these dates were successively pushed forward from 2008 by IP editors in July 2009, October 2009 and December 2009, none of them providing a reference or even so much as an edit comment. I see no reason to think these editors knew what they were talking about, and some reason to think that they didn't.

keep your dvd players —Preceding unsigned comment added by 207.210.51.222 ( talk) 08:29, 19 May 2008 (UTC) this wont effect blu ray dvd , u see ur need a special player with a green and red lazer , thats gonna cost a lot , blu ray is perfact for 20 years easy —Preceding unsigned comment added by Stephenkolo ( talk • contribs) 18:29, 21 May 2008 (UTC)
Look who was wrong 4 years ago. In the meantime, HDTV adoption has become widespread, and Blu Ray, which has become the only physical media for 1080p video offers hi-def 3D at a superior quality over streaming (the infrastructure just isn't there and people also still like to physically own things they pay for). Unsurprisingly, Blu Ray now has a 25% share of the home video market, 40% of the sales of newly released movies go towards Blu Rays. The price of 50GB BD-Rs has come down to ~$3.60 USD per disc. That means, for Blu Ray the price per Gigabyte now is $0.078 USD, whereas the price per Gigabyte for DVD-R now is $0.069 USD - a negligible difference. The price for PC Blu Ray writers is below $100 USD. At the time of this writing, Blu Ray is the only media for long term storage of large amounts of data (eg. hi-res video and images). Properly stored, BD-Rs are expected to last at least 30 years, possibly 100; no HDD lasts that long. At present, there is really no alternative. While I have no doubt that HVD would be a good format, don't expect it to be introduced any time soon. None of the companies that backed Blu Ray have even the slightest interest (or reason) to make another switch for the next couple of years. Until Ultra HD becomes the norm (which could take until 2020 or longer), there won't be much demand for a larger physical format, and even then Blu Ray might still be enough: "On July 20, 2010, the research team of Sony and Japanese Tohoku University announced the joint development of a blue-violet laser, which will help in creating Blu-ray discs with a capacity of 1 TB (dual layer)." The next generation of video game consoles (Wii U, PS4, Xbox 3) will all feature a Blu Ray based storage format. In summary: Go ahead and buy a BD drive for your PC. Blu Ray won't be obsolete any time soon. — Preceding unsigned comment added by 93.193.185.64 ( talk) 15:16, 17 September 2012 (UTC)
>"Generally you're looking at a lifetime of less than 10 years." That is not true. I have talked about this with several experts; for instance Verbatim (Mistubishi Chemical) confirmed that they expect writable HTL BD media (inorganic dye) to last 30 years or more. I own several Verbatim Azo dye CD-Rs written as early as 1995 (=17 years ago), they were stored properly and still work perfectly. Note that Azo dye is organic, and thus much more light sensitive than HTL BD-Rs; so there is no reason to assume that BD-Rs won't outlast CD-Rs. Of course if you buy cheap no-name discs, then you get what you pay for. Hdds certainly are more convenient (speed-wise) than optical discs, but to really be on the safe side you need to migrate your data to new drives every 5 years and keep multiple copies, which makes the price per GB much higher than using BD-Rs. — Preceding unsigned comment added by 93.193.180.202 ( talk) 04:44, 30 October 2012 (UTC)
Can whomever manages this page please fix this? 192.35.35.34 ( talk) 17:31, 17 December 2009 (UTC)
In the first paragraph, the disk is described as having data read by a green laser, while tracking is done by a blue laser. In the second paragraph, however, we are talking about green for data and red for tracking. My question is this: RED OR BLUE? I know it's a simple find & replace job, but I don't know enough to determine which colour is correct. 118.208.105.69 ( talk) 03:55, 24 January 2010 (UTC)
This is all very interesting to me i'm just waitiing for this technology to actually become a reality, but the answer to your question is that the red laser is used to read the data in a normal cd/dvd medium however with blu-ray it uses blue laser hence why its called blu-ray

Removed the bellow from Competing Technologies, clearly it shouldn't have been there. Also I've just realised there are a few typos through the article. Will go through and correct.
"ge has had holographic storage disks since 2009 capable of being played with curent blueray systems, this artical needs to be fixed. disk player costs should be ~$120-500 and discs should be <$50 (cheaper than bluerays to produce and record)" —Preceding unsigned comment added by 117.120.16.131 ( talk) 06:20, 2 May 2011 (UTC)
Among other things, the article lede claimed planned release dates of 2019 and 2020, without references. It's unlikely that any technology company would announce a release date so far in the future. Using WikiBlame I found that these dates were successively pushed forward from 2008 by IP editors in July 2009, October 2009 and December 2009, none of them providing a reference or even so much as an edit comment. I see no reason to think these editors knew what they were talking about, and some reason to think that they didn't.
Please fix my rewrite. It's still pretty bad. But I think it's better. -- BenRG ( talk) 00:30, 31 May 2011 (UTC)
in that HVD_logo.svg on the right, holographic is spelt incorrectly, as 'holograpic' -- 82.153.115.127 ( talk) 10:28, 24 May 2012 (UTC)
Is it safe to say HVD is a vaporware project? The official website has been either a blank page or a domain park since 2012 216.73.201.25 ( talk) 12:09, 14 November 2014 (UTC)
I’ve proposed merging General Electric holographic disc into this page, as that article has little stand-alone value but makes sense as a section of the more general article. Mccapra ( talk) 12:19, 19 October 2017 (UTC)
