The laser world is more than just 445nm. ;) Violet is still one of my favorites. mW for mW violet is still the best burner (and it is pretty to boot)

Yobresal posted info about this new 12X bluray burner. When the price got down to $150 WITH tax and shipping. I pulled the trigger on it.

As usual my photography skillz suck, but you can get the idea ;)


The case is unremarkable. The "top" comes off with the removal of four screws

Here's the inside. You can easily see the sled.
The PCB is easily removed by pushing back a plastic keeper and pulling the ribbon cables

Removing the three screws holding down the spin motor allow the removal of the motor and bracket.
This exposes a couple of screws that hold down the sled rails.

Removing those allow you to lift the rails high enough to slide the sled off the rails and out of the drive.

The bottom of the sled. This sled is different from the Pioneer 12X sled

The top of the sled with the cover removed.
The bluray diode is at the upper left (your left) of the screen.
It looks like a gray 1/2 disc with the pins sticking out.
The red diode is in that gray rectangle at the upper right of the screen

In order to remove the bluray diode you have to lift the PCB and cut the ribbon cable leading to it. The ribbon cable is completely enclosed in the sled. This was the only way I could figure out how to get it cut.

Once the ribbon cable is cut, you can lever out both diodes.
They are held in place with glue.
Here you can see the diodes in their respective heat sinks.
The red diode is a flat "plastic" diode.
The bluray is the standard 5.6mm can package

The diode back has no remarkable markings.
To remove the heat sink, grasped the corners and wiggled a bit before I "peeled" them back a bit.
This loosened the diode for removal from the heat sink

The diode has no unique markings. It is plain except for the square code on the back.
The pins are cut shorter than the Pioneer 12X.
The pins are about as long as the pins in the GGW 6X.
If this diode and the Pioneer 12X were sitting next to each other, you would not be able to tell them apart (except for the length of the pins)

Hopefully in the next few days I can get time to graph the IP/OP

Peace,

Nice work Dave! Only doing what you always do, risking $$$ for the rest of us! Thanks for sharing. I can't wait to see the results from the testing.

Sorry. I got hung up in paying jobs ;) I have a couple of the sleds on the way as well. I plan on testing one of them along side this one

Peace,

Dave;

Good job on the info you provided.

That sled from the Lite-On is made by Sanyo.

The 12x is finally getting where I might consider one.

Keep us informed on your progress please.

12x would sure be nicer than the 6x I have now.

Dave;

Here is the chart from Sanyo on laser diodes :

Since the chart was made, diode manufacturers have stated that they are now producing 320mw & 340mw diodes for 12X BR burners @ for 2-layer writing.
