Discussion Overview
The discussion revolves around the comparison of Blu-ray, HD-DVD, and holographic storage technologies. Participants explore the pros and cons of each format, their potential for future adoption, and the current state of industry support. The conversation includes aspects of data storage, video quality, and technological advancements.
Discussion Character
- Debate/contested
- Exploratory
- Technical explanation
- Conceptual clarification
Main Points Raised
- Some participants express uncertainty about which format to buy, citing the lack of consensus among companies.
- One participant suggests that Blu-ray is better for data storage currently, while holographic technology may be more promising in the future.
- Another participant mentions that Blu-ray has a higher capacity than HD-DVD, specifically 40% more.
- Concerns are raised about the production costs of Blu-ray due to the need for new manufacturing lines, whereas HD-DVD can utilize existing DVD production lines.
- Some participants note that Hollywood seems to favor HD-DVD, despite Blu-ray's backing from companies like Sony and Apple.
- There is a discussion about the technical aspects of blue lasers and their ability to store more data due to narrower wavelengths.
- One participant questions the popularity of dual-layer DVDs compared to single-layer DVDs, suggesting that dual-layer is more widely used.
- Another participant seeks information on holographic storage technology, expressing frustration over the lack of recent research and development in the field.
- Some participants highlight the potential incompatibility between Blu-ray and HD-DVD players, which could lead to increased costs for consumers.
Areas of Agreement / Disagreement
Participants do not reach a consensus on which format is superior, and multiple competing views regarding the future of these technologies remain. The discussion reflects a mix of opinions and uncertainties about industry support and technological advancements.
Contextual Notes
There are limitations in the discussion regarding the definitions of terms like "holographic" and the specific technical details behind the capacity claims of Blu-ray and HD-DVD. Some participants express a lack of clarity on the sources of certain technical figures.

I wouldn't buy any of them right now. Why? Because the companies themselves haven't decided which one to push.
Btw, why did you stick holographic into the list? It isn't a standard it's a technology.

I don't know much about this but from what i'v heard blu-ray sounds amazing. Sony and apple want blu-ray but Hollywood wants HD-DVD.

B-DVD has more capacity than HD-DVD, 40% more.

Holographic is a fancy hollywood theoretical technology that has not emerged from the dark window-less labs yet. I'm personally a blue-ray kind of guy but HD-DVD has already become standard in hollywood. Sony will push blue-ray though. I'm not digging holographic within the next 10 years. Maybe after that.

No one has decided on Blu-ray or HD-DVD. Companies keep flip-flopping on the issue.

Even the current dual-layer DVD (8.4GB) hasn't been made popular yet, why not we just focus on dual-layer DVD? 8.4GB shall be enough to record a good movie!

How exactly is this? Isn't the wavelength of blue light 27% less than red light?Sprinter said:

HD-DVD can go up to 30GB, blue-ray can pack 50GB per layer on 1 disc, however, blue-ray needs a complete new production line, this will pump up its cost, while HD-DVD can be made on existing DVD line with minimum adjustment.

Blue laser has narrower wavelength, so it can pack more info per squared inch.

I am more than aware of this, as you can see from my previous statements. Well, just read my previous statements than you'd understand. Anyone else know where that number comes from?

Dual-Layer is definitely made popular... who the hell uses single layer DVDs except for a bunch of white bellied, red necked, cousin ****ing hill billies?

Holographic?
Hey!
Just wanted to know if anybody got any GOOD stuff on Holographic storage. I did a project on it in 2004 but all I could find was mid-90s journal articles
The tech is super amazing but where's the R&D? Anyone??

blue-ray is supported by sony and hd-dvd is supported by toshiba and some others. as far as i know, both companies can't agree on what standard they're going to use so it could mean that a blue ray dvd won't work with an hd-dvd player and vice versa. making you spend 2-3x more for a dvd you already own.
which you really don't have to by the way, since not having a high definition tv will not enable you to take full advantage of blue-ray/hd-dvd in the first place.
