Hitachi Showcases 100gb Blu Ray Disc

Intamin · 10-04-2007, 08:58 AM

Here are some blurbs and a direct link...

"Hitachi has developed a prototype four layer Blu-Ray disc capable of holding 100GB of data."

"Hitachi, however, claims to have used a standard Blu-Ray drive optical head that's only slightly modified to allow it to read and write data across the four 25GB layers. It's believed this will only require a firmware update to make existing drives compatible."

Pretty freaking sweet if you ask me.

BD100 requires both a firmware update AND new optical hardware:

Quote:

Hitachi used an optical disc drive based on the "GBW-H10N" supporting 4x speed BD recording, which Hitachi-LG Data Storage, Inc. announced in July 2006. However, the company made some alterations to the firmware and the optical system inside the head, to make the player compatible with four-layer BD playback. Frontend signal processing (Renesas) and other circuits are the same as those used in the "GBW-H10N."

This is NOT for movie discs. It is just for recordable discs. It really belongs in the computer section IMO.

If they develop a disc with so many layers it would be a shame not to use it for movies, so IMO it is or rather, will be for movies as well.

Blu has showed the way once again

Did you read the links? Wishing something and reality are not the same thing, just so you know.

Is this where you try to discredit me because I actually know TOO MUCH about this stuff again.

All he sees is "100GB"

Too bad he doesn't understand that a brand new optical drive is necessary to read the 4 layers.

That would mean EVERY BD player INCLUDING ALL PS3's could not play a movie that came out on a 100GB disc.

This is STRICTLY for the Enterprise marketplace.

don't be so paranoid Mr know-it-all, i'm not trying to discredit you, i simply say that if they develop that technology why would they stop short of using it for movies ?
We go to the moon, probe the atom, can talk to someone across the world but we can't develop a multi layer disc for movies though we can for other uses ? hmm it sounds that you are giving too little credit to what could be done. just wait and see and also try to relax

crazyal · 10-04-2007, 10:28 AM

Even at 4x it would still take almost 2 hours to write to that thing. It could be useful, if the disc is cheap enough for security camara's. As for movies, I guess you could use it to fit a whole season of a TV show or a mini series, maybe even a trilogy but again cost and yeild would become an issue.

You are forgetting the limitations of today's hardware. This is not a case of a FW UP. Todays BD drives cannot read a 4 layer disc.

By 2009 there will be approx 7 million+ BD players of which NONE of them can read a 4 layer disc. So is every BD owner expected to go out and buy a brand new player?

Shesh! What am I thinking - of course they will. Isn't that the plan of the BD CEM's? To get people to keep buying new hardware?

Oh, please.

Recordable media is *far* too expensive and time consuming to consider using for mass-market, pre-recorded movies.

That's why *all* mass-market, pre-recorded discs (CD, DVD, HD DVD and BD) are stamped or pressed in read-only media.

One of BD's big mistakes was coming out with BD-Recordable first before perfecting BD-ROM for movies.

That was in reference to you calling people HD DVD fanatics because we knew more than you did about BOTH formats. Trust me, it doesn't take much to do that, but YOU are the one who went that route.

Do you think the can use the Lunar lander in the Space Shuttle? It is about compatibility and cost to replicate. They cannot replicate recordable discs. You have been told this before I believe but you still act like they are the same.

Not really when you consider standard SATA300 & soon to come SATA600 Hard Drives costs a hell of a lot cheaper & have faster data transfer rates. 15GB, 30GB & 50GB are good enough IMO for DVD's. I'll stick with 750GB & 1TB HDD's thank U

Plus if this 100GB ever comes out, today’s BD players don’t have the means to play them.

Well... seeing as they can't get current releases to play

(sorry I couldn't resist, I know it's a trolling comment and I know about issues with earliers combo discs
