Blu-Ray Question

[JimRune]

Someone posted this on the GameSpot forums and I'm wondering if it holds any water:

Quote:

very optical drive starts with CLV or constant linear velocity drives and then progresses to CAV or constant angular velocity.

CLV is good at reading data in adjacent sectors, however when data is scattered all over the disk (as is the case with games) there is a whole lot of slowdown due to poor seek times. CAV does not have this problem.

Both the sega CD and the PSP had CLV drives, and they have both demonstrated poor loading times. The good news is, PS3 games won't be on blu ray. They will be on DVD, just like xbox 360 games. They will not be on blu ray because of the poor seek times from the CLV blu ray drive.

Good. Nothing ruins a game's pace more than those stupid load pauses.

God of War on the PS2 loads fast, saves fast and reloads fast. Prince of Persia, Two Thrones on the PS2 is the complete opposite, IMO.

System specs by Sony show that that their drive is capable of reading CDs, DVDs, and blu-ray discs...so really, its up to the game dev on which to use..

As for the seek times, the only thing I can think of, is that because the BluRay disc holds sooo much more than the DVD, content maybe more hard to find just because the fact that you have to sort through much more content...other than that...there shouldn't be any difference in seektimes as the read times on the bluray and dvd aren't that big of a difference.

Bottom line - game devs are going with the BluRay because they can put over 40gb more content than if they were to use a dual layer dvd...which means either very very long games at the same quality of the content on dvds, or high quality content at the same game length as the dvds...their choice.

its the lasers footprint that is smaller which allows for more storage capasity on optical media disc's..

however there's nothing to say that blu-ray is going to be backwards to current media standards and the dye the media uses when you burn a disc whether it be cd or dvd..

yes load time is a worry but big selling games like GTA needs the space for the map.
It would be nice to have GTA for ps3 in blueray that get the whole city 3x the size of san andreas. It also would be nice to have more cars and buildings to go into.
Of coarse there will be load time and i for one can wait. I hope the new GTA series from rockstar will be better and bigger.
