Pioneer BDR-205 12X Blu-Ray Burner

[IgorT]

This image looks very much like the back of the diodes coming out of the 8X drives.

Don't go crazy until we get a few tested.

Remember the "S03" (and the Alamo)

Peace,
dave

We remember the "S03" (and Alamo not as much, but still)...

Regardless of how they achieved 12x writing, i still want to test ONE 12x diode as soon as that becomes possible....



Otherwise, Dave, what's "wrong" with the above picture? :thinking:

 

[jayrob]

There is solder on two pins, but none on the third pin... (like a red)

I wonder if the pin connections are different??

i bought the pioneer BDR-205 at akihabara. the price is about 24000yen.
i operate the extracted ld at 150mA at 5V. i don't have the laser power meter,
so unfortunately i cannot mesure the laser power.
so, sorry, it is difficult to decide the maximum current level of this LD.

I have already quoted the continuous operating current for this diode at 200ma. Power out was 200mw.
That would be for several thousand hours life.
Sanyo Develops 450mW Blue-Violet Laser Diode -- Nikkei Electronics Asia -- January 2009 - Tech-On!

It should withstand 400ma with adequate heat sinks.
I would estimate power at over 500 mw.

Several here are operating their 8X conservatively at 300ma.

We are awaiting your first 12X operating results.

the second pin is not used in the sled.
i enclose the picture of the LD on the sled.

Those pins look hardy... nice and long also. Thick pins, Jay the pic has the diode pin orientation the same as all 405nm diodes

That would be SCARY, i need my 405nm's to be floating pin!
Otherwise, i believe he just vacuu-sucked the pin really clean? :undecided:


Besides, the second pic - the one with the flat cable still attached shows that the connections go to the floating pins and the can-pin is left unsoldered....

So i think we're safe... :yh: Looks like 405nm's, at least the ones made for drives, will remain floating pin!

Good... this last picture with the cable shows that it is the same as other blu-ray diodes.

I was just wondering when I saw that first picture that looked like there was solder on the case pin, but not on the negative pin...

About time for the industry to accept the C-mount diode.

HMike

Are there ANY Single Transverse Mode C-Mount diodes used anywhere at all?

I kinda always thought of C-Mounts as MultiMode only... :thinking:
Just like most 9mm's....

 

[Tabish]

OMG, it has thick solid pins !!!!!

Or else it would totally suck to snap the 12x pins off......

What are you talking about man? :thinking:

To me it looks like any other 5.6mm diode..

 

[HIMNL9]

It's the macro effect, it look more big, but are the usual pins

 

[IgorT]

Ah, that makes more sense now!

He doesn't know what he is talking about..as usual.

 

[Tabish]

Ahhh. The pins on my PHR's looked thinner.

 

[hisikawa]

I raised the operating current up to 260mA(5.4V->5.1V decrease very rapidly).
If the efficiency is 25%, the output power of the diode
is approximately 350mW.
I am very sad because the diode died suddenly. I don't know the reason.
One possibility is the electrostatic attack. Since the humidity was very low today.
bye.

Damn, that must suck.

Where was the diode when it died ?
