Talk:Holographic data storage

message: "Let's get things straight from the get-go. Holographic data storage is not the future. It is a modern-day laser disc."
I found the above statement of opinion at the top of the article. Obviously that's not appropriate for an encyclopedia, so I removed it, and I am copying it here.
I don't think the laserdisc is a very good example of a dead-end technology, because the technology of laserdiscs became used in CDs, CD-ROMs, and now DVDs, HD DVDs, and Blu-ray discs.
Holographic storage isn't a product like the laserdisc, it's a technology, like the internal combustion engine.

I agree with the above comment. What is the essential thing about holographic data storage that makes it different, and potentially more useful? What is the common media it's on? Simple, basic questions are not answered. From my brief readings, it seems that holographic data storage is a new ish way to store information on things that are like traditional CDs or DVDs, but are able to slow down the degradation of the data considerably. Why can't that be at the top of the article? A tech or business journalist would best be able to take care of that. Andaroocorp (talk) 02:45, 28 April 2008 (UTC)

message: "The write-once, read many (WORM) approach to data storage would ensure content security, preventing the information from being overwritten or modified."
"Like other media, holographic media is divided into write-once (where the storage medium undergoes some irreversible change), and rewritable media (where the change is reversible)."
Which one is right? Is it optionally write-once? This should definiteley be cleared up.

replies: text: Holography is a technique whereby 3-dimensional information is approximated in two dimensions by changing the angle of the light reading/writing it. Thus "holographic" data storage is named correctly (it is no marketing ploy, they aren't even marketing it yet), as it uses 2D approximations of 3D data (e.g. the cone-shaped data pattern of an  HVD) to increase the storage capacity of an optical disc. It can be contrasted with  3D data storage. Rather, it is Mr. Roddenberry who incorrectly used the term "hologram" to refer to a  volumetric display. Like many technical and scientific terms, "hologram" has a popular meaning which differs greatly from its technical/encyclopedic meaning.107.10.53.28 (talk) 04:47, 4 August 2011 (UTC)

message: However, claimed longevity of storage has, in the past, proven to be a key indicator of
 shorter-term reliability of storage media. Current optical formats – such as CD – have largely
 lived up to the original longevity claims (where reputable media makes are used) and have
 proved to be more reliable shorter-term data carriers than the floppy disk and DAT media they
 displaced.'''
The first sentence makes no sense. Is it saying that if someone claims a medium will last for a long time, it won't?
Secondly, CD-Rs (I assume that's what it means, people can't press their own CDs, CD-Rs are based on photochromism, not embossing.) have NOT been proven to reliable, quite the opposite. CD-Rs tend to fade over time. Their projected reliability has been shortened from 100 years to about 5. Moreover, CDs did not "replace" DAT/DDS. For one thing, the application domain is entirely different. Magnetic tape is several orders of magnitude more reliable, and is the preferred archival medium for long term backup.  — Preceding unsigned comment added by 69.153.136.217 (talk) 18:09, 17 September 2012 (UTC)
