Sanyo's New High-Power Blu-ray Laser Will Burn 100GB Discs at 12x, Someday
Posted by John Mahoney at 5:15 AM on October 7, 2008
Even though the blank media companies have been touting 200GB Blu-ray discs for years, mostly as part of the psy-ops war against HD-DVD, the largest discs today's players and burners can handle are dual-layer 50GB blanks that burn at up to 8x. A new 450 mw blue laser diode unveiled by Sanyo, however, will enable players to read and burn four-layer 100GB discs at up to 12x speeds. Actual drives with the new laser are still probably a year or two away. [Computerworld]

This will be great for backups. I am so sick of messing with those clunky tapes.

Question . . . if they have a laser that can burn a 100gb 4 layer disc can something like the ps3 read that or does it require to have a different laser for reading it as well as burning it.

@invictus13: I'm pretty sure you'd need a new laser to read a 100 GB disk, or at least a firmware update. However, I doubt that early bluray drives have that much hardware overhead built into them that they'd be able to read through all those layers, but I could be mistaken. In short- you'd need a new drive.

btw, the computerworld article says these are 450mW. For comparison, a 75mW green can burn through electrical tape. Blue at the same power is better at cutting/burning than green. And thanks to their widespread use in blueray, blues will eventually be cheaper than greens.
The only problem is a bunch of idiots abusing them and the government responding by putting stricter laws in place governing their use.

sweet. The faster speeds are possible because the lasers are more powerful. More powerful lasers! hmm....

As a non-BD owner I do have some questions. Do BD discs suffer from DVD layerchange issues (basically watch for a pause in the movie, which is often hidden by a cut scene, in which audio drops out entirely)? If so, does that mean I would need to suffer through 3 of these on the 4 layer discs?
Or are they sufficiently advanced enough to read ahead and not suffer from this?
Thanks...

We might actually be able to burn a BR disc in under 8 hours now... Thank god. I've been working with WHV on some BR projects and I know they're happy to see the tech improve.
