New Blu-ray laser can result in write speeds of up to 10x

zekrahminator · Feb 23, 2007, 03:59 PM

Blu-ray disks are currently limited to a slow 2x write speed, as are the burners. Fortunately, Nichia Corporation looks to change that.

Quote:

Nichia's new laser diode is able to emit pulsed light at 320mW, while it offers a stable operation of 1,000 hours, according to the company. The diode could be used for optical discs including Blu-ray and HD DVD, allowing 10X speed recording with a double-layer disc and 2X speed recording with a four-layer disc.

Nichia hopes to make these available by mid 2008. Of course, Blu-ray disks have to be made that can actually support this gigantic boost in burn speeds.

Sweet

Sweet now if we could just get those nasty prices to come down!

Nice, if I could buy a bluray drive for under 100$ that would be nice, same for HD-DVD drive.

WarEagleAU · Feb 23, 2007, 06:27 PM

Agreed. Lower prices and this is a sweet deal. However, 1000 hrs of operation seems paltry. How about years of operation instead

That's 1000hrs WRITE stability... not read. Read is pretty much unlimited. Problem is that 320mw is a HUGE output power... needed for burning at this speed... and the thing basically fries itself.

Yeah, aren't DVD burner diodes around 50mw?

I think it's 60, while CDs are 30. I want to say there was a big hooplah when the first burners for DVDs were coming out, and it was double or some such nonsense. I could be terribly off my mark and thinking of something else though.

bit of a weird question, is the 2x speed of bluray the same as 2x speed of dvd-rw? because before i got a dvd-rw and had my old teac cd-rw 16x. Writing a cd-r @ 16x would take probably more time as writing a near full dvd-r @ 16x ? so is it in comparison or do i just remember cd-r's taking longer when infact its the same speed.
