10x Blu ray Burner from Buffalo

Searched and found this. Where did this come from

techPowerUp! News :: Buffalo Launches Two 10X Blu-ray Writers

10x single layer, 8x dual layer. Is this just the same old stuff we already have

lets hope its new!

Yeah I searched single vs dual layer and not much came up.

Oh and off topic dark for the laser you got me how much does direct press have over say a larger heatsink without it

Edit: 777 posts with 7 rep, lucky?

it just provides more surface contact to the diode, cooling it slightly faster.

SightFX, and IgorT could devulge more on this topic.

So does anyone have any info?

Not until somebody buys one and checks it out. I don't have any contacts in Japan.

Peace,

Alright thanks dave I didn't know if it was just an 8x called a 10x or if it's really something new. I'm surprised more people aren't interested

I'm interested. I just don't have any Japanese contacts for it. The newer drives are first released in Japan.

The reported speeds are different. This Buffalo (LG) 10X reports:

single-layer BD-ROM burning speed of 10X, and 8X for dual-layer discs,

My Pioneer 203BK (8X) data sheet shows 8X for single layer and 6X for double layer:


So the 10X is reporting faster burn speeds, but we don't know if the faster speed is the result of a new, more powerful diode or just better optics and/or software.

Peace,

MMM thanks dave. Cool stuff. I hope we get some better diodes

I don't mean to threadjack but at what mW do 8x blu ray diodes use to burn discs? When they are harvested and installed with a driver aren't they pushed with a higher current?

The reason I wonder is I saw that 12x's will burn at 450mW. But 8x's can already be pushed to 500+mW. I'm looking to make a ratio to find out how much output power in mW can be expected from a 12x.

?(Unharvested 8x mW power) / 500(harvested 8x mW power)= 450(unharvested mW power) / X(future harvested 12x mW power) Understand?

Unfortunately, we do not have this kind of info. We do not get data sheets for the diodes. We estimate rated power by testing the power slope of a diode and taking note of the location of the first "kink" in the slope.

We push diodes beyond what the manufacturer designed them for. However, the output needed in a bluray burner is controlled/limited by many other extraneous variables. Most of these are not restrictive on us.

I can GUARANTEE ytou that the 8X diode is NOT rated to go to 500mW. What is it rated to? We don't know.

Unfortunately, until we get one into our hands, there is no way for us to know how high a 12X can be pushed.

Peace,
dave

Thanks Dave.

Well post here or I guess make yyour own thread if news comes out. How sick would it be if a place like tigerdirect or even a reseller that sells here sold us 10x diodes and they weren't pushed 8x's

how about if the 10x is able to hit 600mw without breaking a sweat ?

hmm.................

we may have to push 450ma into the thing..

Uhm ..... are you sure ? ..... (J/K )

Yes, and other than this, seems that none keep in consideration the optics and beam paths of the sleds, thinking about powers used in burning process ..... if you considerate the pulsed driving, the diaphragms, the diffraction grating, the focusing assembly, the filters and mirrors, and so on, i think not more than 20 or 25% of the power emitted from the diode reach the disk, in the burning process (anyway, considering that this power is focused in a spot that is usually between 0,3 to 0,35 microns, depending from the quality of the assembly, it's more than enough )

BTW, just wondering ..... if we only can find a way for focus the power that we usually get overdriving these diode, in a spot small (or also just close) as the one that is used in burners, do you imagine what the hell of pen-size burners we can get ? ..... like, 100mW of PHR, condensed in one micron focusing point, instead usual 1/20 of mm of the "good" glass lenses assemblies ? ..... think it can cut and cauterize your skin before you notice the heat, LOL
