It is PS3 able to read 4 layer BD ?

[Shifty Geezer]

I think devs have better things to do and easier options like redundant data...

This is the other possible take on the 4 layer disk though. Expand your data with masses of duplication to keep seeks short. You'd only need to switch layers at certain points in the game to make the transition to layers, like a disc swap. I don't know what realworld benefits data duplication will have versus developer input though, and if you're got an HDD to cache off, I imagine it doesn't hold a lot of appeal.

4-layer BD-ROM support for PS3 possible via firmware update this sound from Hitachi where its annouce 200GB BD-ROM disc.

Don't tell Kojima, he may delay MGS4 some more to put on more language tracks like Urdu, Swahili, or even Afrikaans

If I remember correctly, this is ONLY for (4-layer=100GB) BD-R discs...not BD-ROMs (BD-ROMs are only for studio movies and games) BD-ROMs are limited to 50GB for the near future.

If 100GB BD-ROMs were available, I believe he would.

 

[PS3MAN]

Yes. he'll.

If the next-gen goes with BR for optical storage (just assume with me for a moment please) then why would we not see a multi-laser reader? I'm not sure of the technology here. I do know I had a Plextor high speed CD ROM that had like 7 lasers in it. No need to spin the disc at insane speeds and some serious transfer rate. If hdd's are going to be optional, or don't offer a large enough performance advantage over a high-speed optical drive, will this be a possibility? I would assume the part itself (the laser/read head/whatever the hell it is and Plextor did)will fall a long way in price by the time the next-gen arrives. Why not just use this for your base model. It would seem to be a natural extention of something which has already been done with old CD tech.

Now, I don't remember how much faster the reading was, just that it was damned fast, but the drive could spin at a reasonable rate, there wouldn't be as much concern about SSD v. Mag Hdd, and what will be ready when. You could conceivably test this now. How much faster would this kind of drive be? Would it be enough? Most here seem to think that there will still be an optical drive with physical media, for a host of retail/psychological and bandwidth/consumer penetration reasons,so why not look at this route? Maybe you have a 200GB disc and a 7 laser optical drive. What kind of speeds (seek and transfer rate) would that net? Would it be enough to justify the hdd (of any kind) being optional for those who want movies/large file downloadable content and just a small bit of Flash for save files and the like? Hell, why not make it a re-writeable for Arcade/PSN games. A standard 25gb disc would seem to be plenty for that kind of need.

Just throwing out thoughts. No warranty is implied or stated.

Mod: I think I posted this in the wrong thread. I was reading two at a time and this was a natural extention of reading both this thread and the "Guess the Next Next Gen...." thread. Please move if it fits better there. Thank you.

IIRC those multi-read CD-ROMs were great at improving data transfer rates, but they didn't do anything about latency, which is the whole reason even BD games move latency-sensitive data to the HD.

 

[PS3MAN]

Pete right.

 

[Silenti]

They didn't improve latency? I know I have no idea how they actually arranged the lasers, but that seems counter-intuitive. Just as a side note, if the lasers were arrayed around the disc how could it not improve latency? (Not that I fail to believe you, just trying to understand why, with what amounts to multiple read heads, it wouldn't find the information much faster.)

Thanks

Benefits for games? Not so much. Hideo Kojima was apparently quoted as saying a 50GB Blu-ray disc is too small for MGS4, but I have a funny feeling he was either mistaken (i.e. filled a 25GB disc) or was badly misquoted by the press. I guess we'll find that one out when the game's released. Surely someone will pop it into a PC and give us a number.

On the last Kojima Prod. podcast, Ryan Payton mentioned this issue. Original plan was to release the game on 25GB disc, but soon they realised that they need more. So Kojima went to sony bigheads and asked for 50GB. (apparently Ryan saed that every 50GB blank disc is already bought by movie studios, for a year ahead. There is simply no blank discs and recording time in facrories for Kojima. But somehow they managed[/b]).

And then he mentioned that even now with 50GB disc they have problems with free space.

The BD-50 shortage rumor was (is ?) rampant. That's why I pre-ordered MGS4 early, just in case.

I finally found a review link that still works and that confirms my memory hasn't yet turned to mush. It wasn't multiple read heads, just a more sophisticated single one. That might mean correspondingly slower access times b/c the pickup is that much bigger and heavier; see the second page of the article for dueling results.

Multiple read heads would be interesting. Cell certainly seems like CPU enough to handle that much info, and lasers may be cheap enough by the next gen to consider it, and (to be reomtely on-topic) 4-layer BDs would seem to offer a greater reason for quicker access that would obviate a HD. Then, depending on how broadband speeds had progressed, the next-gen console might get away with improved optical latency, a relatively small flash storage (that would get either cheaper or bigger over the console's life), and fat internet pipes to stream all the media content the user had bought, rather than store it locally. But I suspect that's as far-fetched as multiple pickups, at least for the next 5-10 years.

 

[Silenti]

Dang. Here I thought the tech worked differently than that. Too bad. Multiple heads with cheap mass storage, woulda been a nice idea. Ah well. Thanks for the link.

That'd be a killer for the game if it was limited by numbers.

 

[patsu]

Some insiders have kinda denied the issue. But I pre-ordered before his post. Still... just peace of mind for me. I am still waiting for GT5, SingStar and Valkyria of Battlefield here (Hurry up !).
