Don't you guys think the consept pf the new blu ray disk is awesum! up to a 25 gb capacity or something. but now that i know about it i want it!!! it would making backup so much more easier. now does any1 know when they are going to be selling this to the public. becos i have not seen it anywhere for sale and i have read that there are drives available? so it would be useful to know. and one off the topic. who knows when hl2 exp is going to be released?

1.12 When will I be able to buy Blu-ray products?

If you live in the US, you will have to wait until the Blu-ray launch which is scheduled for May 23, 2006. While we've heard very little about the launch plans for the European market, we expect it to follow shortly after the US (some products might launch earlier).

Yes the PS3 is comming out with Blu-ray..

Now all I need to do is rob a bank so that i can get a PS3 with games and a Blu-Ray writer and media..... when its finally released

i read that samsung is the first to release the blu ray drive? ya in may. you guys think its going to moere expensive? cause then we would have to wait like a year - year and half before its in any kand of purchasing range.

As with all new technology they will be very expensice at first. Remember paying R1800 for your first DVD burner ? Also don't rush out and get a Blue-ray only burner / player. Some top manufacturers are looking at making devices supporting both Blue-ray and HD-DVD. That way you are covered.

WHAT?? I paid R 2700 for my first HP 2 speed CD-Writer!

Blu-ray may be very expensive, i think. Because a 9GB DVD is already vrek expensive, imagine what a 25GB one will cost - also, i doubt all current DVD players will support it - so it may not be a success!

So THATS how much profit the places like rectron made!!!!

Sony announced Blu-ray will go on sale in the US on 23 May - around $30 per 25Gb single-layered disc.

@kankuro - How did you know i got it from rectron?

ok,all very good it being able 2 take upto 25gb...but how long will it take 2 write 1 disk full??? bout an hour? maybe even 2?? any know?

and how long will it be until they have both blu ray and that other format,i think its sumthing like HD DL or sumthing(was mensioned earlyer on in this post)

At 2x (about 8990 KByte/s) it takes just under 44 minutes.

Blu-ray discs won't be able to be read by any current DVD players as it uses a completely seperate laser technology.

Another nice prospect of Blu-ray is that they come in the dual layer variety too, meaning you get 50GB of data on a single disc...

As with many emerging technologies, tho, they will start piggybacking it onto regular systems. So, you will get a 'DVD player that supports Blu-Ray' long before Blu-Ray movies are widely available.

Edit: And the competing format is HD-DVD (High Definition DVD), and it uses a red laser technology like current CD and DVD drives, but still incompatible with them.

...I know this...

All I was saying is that the DVD players which you find in most peoples houses today (ESP. South Africa) will not support Blu-ray discs. I agree (and have even seen videos of them) that there will be DVD players that are able to read Blu-ray discs. When I was talking about them not being able to be read in current DVD players I was reffering specifically to Blu-ray discs (not HD-DVD) and part of the reason they are not able to be used in current DVD players is that they use a blue laser. HD DVDs do not use the same laser technology as DVD players. DVD players use a red laser while HD DVD players use a blue-violet laser.

HowStuffWorks.com wrote:But three important differences allow them to hold quite a bit more information than DVDs:

* They use 405 nanometer blue-violet lasers rather than 650 nanometer red lasers.
* The pits are smaller and the tracks are closer together.
* They use more efficient compression to cut down the size of the files they store.

ok dam who ever put that link in to the HVD thanks!!! Dam people they busy chuning its possible to get a 3.9tB HVD!!!! WTF and they want to release a HVD 400gB this year!!!! i know none of us are going to get our hands on this nor shall we have enough money for this in quite a long time but DAM!!! imagine carring around a cd looking disk wich carries 400gb!!!! dam thats bigger than both my hardrives put together!!!! lol. me want. any1 works for nasa here? or could lone me a million rand to get started

CD = infra red
DVD = red laser
HD-DVD = violet blue laser
Blu Ray = blue laser

The light wavelengths decrease the further down you go. Data storage increases with smaller wavelengths. The really bad thing about Blue Ray is that you will need to have a internet connection everytime you play a movie so the player can check if the movie is a known pirate copy and will permanently disable itself if you are playing what it thinks is a pirate copy.

HD-DVD allows a managed copy to be made. Blu Ray is the better tech but after the s..t Sony pulled with the rootkit, I don't know if I will be purchasing Blu Ray.

BTW they have quad layer Blu Ray in the lab (100GB)

Ah, I stand corrected =) Thanks for the extra info.

Hex_Rated · Post by **Hex_Rated** » 09 Mar 2006, 11:55

I originally thought HD-DVD was upper red spectrum laser until Rikkelz posted. Isn't violet after blue (blu ray) in the spectrum? Something's not right.

Post by **Synkronos** » 09 Mar 2006, 14:22

The wavelength is not all that determines disk size. All it does it determine maximum theoretical data density.

Hex_Rated · Post by **Hex_Rated** » 09 Mar 2006, 15:01

It is a major factor, but I should have said data-density not storage size. You could say the other factors are layers and the size of the disc. Imagine how much data a quad layer laser-disc sized (old LP size) blu-ray disk could hold.

Another side effect of having a high density disk is that the max data transfer speed is increased at a constant RPM. RPM is what limits us to 52x CD or 16x DVD transfer speeds. 16x DVD is much faster than 52x CD (data tx not angular velocity) because of the increase in data density. The sensor tech is probably what will limit blu ray or HD-DVD to 2x on launch.
