Sanyo Electric Invents 12x High-Speed Blu-ray Laser

malware · Oct 7, 2008, 07:07 PM

Sanyo Electric Co. said on Monday that it has created a new blue-violet semiconductor laser that might hold the key to the future of Blu-ray. According to the information given by the company, this laser can emit a beam of 450 milliwatts, which is about double the power of Sanyo's current highest-power laser for Blu-ray Disc systems. The higher power means it can write and read data on discs with up to four data layers and at speeds of up to 12X, Sanyo said. Each recording layer on a Blu-ray Disc can store 25GB of data, and the highest-capacity commercial discs currently have two recording layers. A four-layer disc would be able to hold 100GB of data, enough to store up to eight hours of 1080p video content. At 12x recording speed writing a four layer 100GB Blu-ray disc will take just around 10 minutes. That's the good part, unfortunately approving the 12x laser from the Blu-ray Disc Association and putting it into mass production can take two or even three years.

why so long?

Uhhh

8 hours of recording times 60 minutes is 480 minutes divided by 12, the speed of writing, is 40 minutes to write a disc of 100GB. Where do they get 10 Minutes? Further, if it could do 100GB in 10minutes, that would be 10GB per minute or 166MB/Sec sustained! Not sure we have any hard drives that can do that?

Fail on the time to market.

BR is still fail. Mebey after it is pried out of Sonys hands and let loose without all the DRM. I refuse to have anything more to do with DRM than absolutely needed.

I don't think that's how you work out the write speed of a disc.

Doesn't sound right at all to me. 1x on blu-ray is 36MB/s multiplied by 12 is 432MB/s. At 435MB/s sustained *in theory* it would only take 200 seconds/3.3 minutes to burn 100GB of data, since we know discs don't burn at sustained rates, it's obviously going to take longer than 3.3 minutes, but 10 minutes seems entirely realistic.

But as you said, hard drives won't be able to keep up with that. Maybe this'll make SSDs more attractive for the close future as an SSD would most probably be the best thing for getting as close to 12x blu-ray as possible.

DRM isn't really an issue when you're watching BD movies on your PS3 through your TV though, plus it's already easy enough to rip a blu-ray onto your PC and convert it to an MKV video.

Yep, too expensive. It might have won HD-DVD but failed the consumers:

It needs to be half the price on players and discs for me to even consider going BLU someday.

If Sanyo is reading this, congrats. Either way guys, Blu-Ray is coming in for a landing and there is nothing you can do about it. I kinda like Blu-Ray too since it stores a helluva lot of data, replacing the flash drive if the price-aware consumer already owns a PC with Blu-Ray features, which they will most likely have after unnecessarily throwing away their PCs just because they think Norton is too pricey and visiting the jip-worthy employees.

I love how they photoshop the laser... as if it is visible!

The whole image is cg, not only the laser.

10 minutes for the 25GB disk mate

Digital downloads and cheap high capacity HDD, that is my choice. There is plenty of room for additional storage on my rig and it is air-cooled and hot-swappable.

I'm not aware of any Media Center platforms that support mkv files though. Having a bunch of those in a movie folder wouldn't be very useful to most people.
