Blu-Ray: hard drive on a disc?

[two]

The next generation in DVD technology will let consumers carry the equivalent of a hard drive on a disc, but what are they supposed to do with all that capacity? Interact, supporters say.

Manufacturers fancy a reciprocal relationship in which a consumer, before watching a Spider-Man movie in high-definition video on DVD, downloads and stores on the rewritable portion of that same disc a video game or trailer for the next Spider-Man sequel. The consumer would also be able to update those games and previews as new versions come out--and give studios the opportunity to make more direct pitches. That's the vision for Blu-ray Discs and broadband-connected recorders that Blu-ray backers described in a recent press tour.

PS3?

Aren't they saying the amount is similair to that of a harddrive?

 

[Carl B]

I don't think the drive in PS3 will have any write capabilities whatsoever myself.

I don't think the drive in PS3 will have any write capabilities whatsoever myself.

I think that is a safe bet. For the cost of adding burning ability to the PS3 they could probably just add a 20gb HDD.

While this idea rather novel, I don't think it'll be implemented any time soon.

I read somewhere that blue-ray could read at like 138MB/s, which is much faster then any HD afaik.

I read somewhere that blue-ray could read at like 138MB/s, which is much faster then any HD afaik.

But what about access time, or max. # of rewrites?

138 megabit per second more likely (17.8MB/s). Which isn't bad for an optical drive, mind you.

At 138 megabyte, the spindle would probably be spinning so fast the centrifugal force would shatter the polycarbonate disc.

Yep, and access time will likely not be in the same league, as Snyder implied.

I'm also not sure what you'd need to read at 138MB/s (excruciatingly high-res HD FMV?). Mb/s sounds more reasonable.
