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.

replies: text: Interesting point.  One idea is multiple HVD's could be "burned" simultaneously by using one very powerful laser and one data page and a light splitter to simultaneously burn all the HVD's.  Obviously lots of design issues to be solved before thats a reality, but if it works then say 100 HVD's could be burnt in one batch.  Another thing is there is no limitation to a single burning head - multiple heads could be used to write the disks quicker. The problem you mention looks like it'll be a problem with many next-gen formats.  82.21.25.116 (talk) 19:12, 25 May 2008 (UTC)

text: Yes a factory of these machines could do it. Aside from that, the read rate would more then justify the use for anything if it is really 1 gig/sec. I mean come on... two seconds and POW!

message: This technology could be instrumental in the effort to solve chess.  Chess tablebases take up a huge amount of space, the HVD could potentially solve the space problem. Dionyseus 11:35, 8 December 2005 (UTC)
replies: text: You're talking 1050 legal positions, according to Computer chess.  That would exceed the capacity of an HVD by a factor in the vicinity of a duodecillion.  In point of fact, it will be physically impossible to store all possible chess positions on the planet Earth, since that only consists of around 1050 atoms.  And finally, the computational complexity of solving all those positions is utterly prohibitive with current technology; if we had a billion computers solving a billion positions per second, it would take 1032 years for them to solve chess, ten sextillion times the age of the universe.Or, in short, these aren't going to help a whole lot. ;) —Simetrical (talk • contribs) 05:23, 27 February 2006 (UTC)

message: 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?
*It isn't actually InPhase that is doing it, but DaTARIUS.  See my above comments (and hopefully my addition to the article if it doesn't get removed) that has time tables and file sizes (300GB to 1.6TB in 2010).   Let's talk about that ;¬)  Grendelum 03:29, 26 February 2007 (UTC)

message: I removed the following sentence:
:(For comparison, the red laser in a consumer CD-R or DVD-R drive is 0.1–0.25 watt)
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)

thread_title:  What is this list? 

message: 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?—jS 23:27, 8 August 2007 (UTC)

thread_title:  10 TB is NOT 1 petabyte 

message: 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.

message: 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.
