Now that is some serious storage!

spart

The CD-ROM on my Rev. B iMac is turning into an 8-Track player quicker and quicker...

eman

Woah :eek: ... That really holds ALOT.

spart

Man...before DVD's barely outspecced my iMac's hd in terms of storage...I need a new HD.

That's a fvcking rip. I hope we don't see anything for at least another 5 years. DVD is just getting widespread use. An audio format is finally coming and now people want to move to another disc entirely? WTF. These media should have at least decade long life spans. CD has had an acceptable life, DVD has just started and people want to retire it already? damn.

the milkman

I don't think that they'll replace consumer DVD players because it really wont be cost effective for some time.



[quote] Adoption of the Blu-ray Disc in a variety of applications including PC data storage and high definition video software is being considered. <hr></blockquote>



I would like to see it focus on data storage and a "professional" DVD format.



[quote]It is possible for the Blu-ray Disc to record digital high definition broadcasting while maintaining high quality.<hr></blockquote>



Movie theatres could use this instead of film.



[quote]By employing a short wavelength blue violet laser, the Blu-ray Disc successfully minimizes its beam spot size by making the numerical aperture (NA) on a field lens that converges the laser 0.85.<hr></blockquote>



Because of the different laser, I don't believe that it would be backwards compatible with current DVD's (I could be wrong). Plus that would piss off a lot of people, especially those with large DVD collections (like me!! )



[quote]They are also aiming to further enhance the appeal of the new format through developing a larger capacity, such as over 30GB on a single sided single layer disc and over 50GB on a single sided double layer disc.<hr></blockquote>



:eek:

[quote]In addition to actively promoting the new format throughout the Industry, the nine companies listed above plan to begin licensing the new format as soon as specifications are completed. Licensing is expected to start around spring 2002. <hr></blockquote>



At least it will be a while before things really get going on this so it will be fun to watch.

wrong robot

though if a more consumerish type drive is released...thats a movie lovers(or pirates) dream...Imaging one disc storing like 4-6 movies in good quality!....or like 100 movies in so-so non dvd quality!



wow....27 gigs is just under my HD capacity!



I think that this COULD be implemented for prosumers...the guys that are really rich(or at least well funded) and LOVE getting new toys

there would be a small market for such an expensive yet wonderful device but there still would be a market.

cdhostage

I hope the Superdrive 2 is Blu-Ray capable. Never mind that they'll need a total of three optical assemblies to make it work! one for CDs, one for DVDs, the last for BluRay!

cdhostage

While we're at it, let's hope Apple releases a BluRay recording device that handles double-sided, double-layered disks. 200 gigs baby! I can make backups of my entire HD finally!

macsrock

just when i get to thinking how cool a dvdram/r drive would be( and how i could double my hd with 4 discs) this comes out. i could multiply my hd by 1.5 with one disc :eek:





BTW, i have a 20 gig hd(cube)

matsu

This is crap. I hope it dies. Why not sell us dual layer capable burners for the DVD spec we already have? Or start selling drives that read both sides of the DVD? There is an 18GB spec for DVD is there not? That ought to comfortably take consumers through the next ten years, and retain backwards compatibility with a huge installed base of CD audio, and DVD movies.



I know technology is supposed to just get better and better, but there needs to be some stability in media of distribution and exchange. People want to spend some of their money on music and movies too, not just on new kit every 18 months. Look at TV, and Radio. If a new TV format came out every 2 years (so people had to go out and get a new set or decoder to recieve programming) consumers would be pretty pissed off. It might be a good idea for governments to regulate and approve disc/publishing media aswell as broadcast media/signals.



We shouldn't have to deal with a new disc format for at least 10-15 years. CD gave us a good 15 years, DVD ought to give as much.

preston

stop bragging about your big hard drives.



My pecker is probably bigger than yours but i dont go around posting it

bunghole

In ten years 27 terabytes will be considered small. (confirmed)

smacsteve

Why don't you people stick with talking about what you know about?

ferro

I remember hearing about blue laser tech a while ago... but 27Gigs... :eek:



thats more than twice my hard drive... on one side of a flat cd-like disk... <img src="graemlins/surprised.gif" border="0" alt="[Surprised]" />



hard drives are going to go the way of the dinosaur...



I could get a multi-pack of 405nm blue-violet RW discs and a RW drive... and have more than enough storage than I could ever use...



this is Awesome... imagine a double-sided disk at "54GB" A normal size Disk!!!!!...



Imagine one of those mini-discs could hold 10GB or a "double-sided" mini-disc holding 20GB!!!... think about it... the size and thin-ness of a mini-disc holding 20GB... <img src="graemlins/surprised.gif" border="0" alt="[Surprised]" />



Imagine how much storage a handfull of double-sided disc/mini-discs could hold...



and it looks like even one-sided normal size discs may even get more packed onto them...



[quote]They are also aiming to further enhance the appeal of the new format through developing a larger capacity, such as over 30GB on a single sided single layer disc and over 50GB on a single sided double layer disc.<hr></blockquote>



that makes everything I just talked about even better, this just makes me drool...



I cant wait for "Holographic Storage"... thats right around the corner too... that should blow this out of the water...



its a startrek future...

This technology has been around for a while I think, but it is only apparently now that it is being standardised (by the bigwigs on the DVD forum etc).



It is not backwards compatible (I don't think) with current DVD standards, and blue lasers are very expensive so I think you can rest assured that we won't be seeing the tech in 'consumer' players/recorders for a long time (remember that DVD has been around for almost ten years now, and we still have different standards for recording).



Once it does arrive I am sure that it will merely be the 'next stage' of the larger storage / smaller hardware process.

27gb is nothing compared to what these guys are doing:



<a href="http://www.c-3d.net/product_frameset.html"; target="_blank">http://www.c-3d.net/product_frameset.html</a>;



FMD ROM Disc and Drive

The introduction of the Fluorescent Multi-layer Disc (FMD) smashes the barriers of existing data storage formats. Depending on the application and the market requirements, the first generation of 120mm (CD Sized) FMD ROM discs will hold 20 - 100 Gigabytes of pre-recorded data on 12 - 30 data layers with a total thickness of under 2mm



Future Disks & Cards

By adding layers and taking advantage of blue laser technology, second and third generation cards and discs will have capacities up to and exceeding 1 Terabyte (1,000 Gigabytes). In addition Read/Write versions of disc and card are planned.

Hell yes! Crystal storage! I had forgotten about this one.

I agree, that is why as far as this being a consumer replacement for DVD, I don't think it will happen. Like DaveLee pointed out, they still haven't settled on one standard for DVD recording. I personally would also like to see how much they can squeeze out of the current DVD spec.

I have to disagree there. People are always wanting more storage capacity in everything, 10 years is a long time, here is a pic from a computer from 1989 and see how far we've come since then.

I can't remember where I read this (possiblly the newscientist.com web page or maybe the bbc). But one of the major advantages of the blu-ray disk is that you can record to it faster than you can to normal DVDs.



This means that you can record at a higher quality in real time (i.e. in set top dvd recorder boxes). Apparently it is suitable for recording HDTV quality images (where as normal set top DVD writters cannot, they have to compress more and lose quality to be able to write fast enough).



incidentlly, people are correct you cannot read/write old style DVDs with blu-ray tech. However it should be possible to put the required tech in the same box.



My personal opinion, is that the companies will not even try to replace standard DVD with blu-ray. Movies will continue to be released as they are now. Blu-ray will come in to its own for the home recorder front. especially if they can keep the cost down (tivo, eat your heart out).



By the way they were talking about early models being relased next year (probablly at some hideous price, even the most die hard earlly adopter will balk at paying).



I hope this does succeed, even if its just because its got a cool name. I want bright blue coloured (yes I'm british I get to use the proper spelling of the word) discs as well.







spelling and grammar

I am not sure about higher speeds but given it has a higher wavelength I suppose it plausable...

Some things about capitalism tick me off... I am sure they wont even give it a worthy attempt...



I am still a fan of the future of holographic crystal storage... I want a isolinear optical chips database with a few hundred chips, each chip to equal 2.15 kiloquads... <img src="graemlins/surprised.gif" border="0" alt="[Surprised]" /> Whatever that means... I am sure its HUGE...!!!

I can't WAIT for this technology to come out. There will probably be DVD/Blu-ray Disk/CD/MP3 players soon after the debut. It doesn't make enough sense for there not to be. I have a Panasonic 16:9 34" TV that's HDTV ready and I would LOVE to see that format on my screen. Digital is great, but the compression artifacts aren't exactly subtle at times. I say bring on Hi-Def video. It's about time.
