So, today my boss went slightly insane and decided to buy a couple 8x bluray burners... The only ones available in town were the lg bh08ls20.
Since I haven't seen anyone disassemble one before, I figured I'd post pics of the teardown process.
Here's the label on the drive:
After removing the four screws on the bottom of the drive, here's what the inside looks like:
Here's a view of the barcode and numbers on the sled in case anyone can make any sense of them:
I suppose I should have taken more pictures, but I was understandably excited... At the base of the rails that hold the sled, there's a couple screws holding in a white piece of plastic that holds the rails in place. After removing those screws the sled and its rails pop right out. There is another barcode on the side:
Here you can see the bluray diode itself, mounted into a small heatsink and glued flush in the sled. To get this out of the sled you'll need to remove the top cover of the sled (a thin metal shield that's glued in at each corner), then use a screwdriver to push the diode and its heatsink out from the inside.
And here's the diode in its heatsink, removed from the sled:
To get the diode out of its heatsink I tried a couple things... At first I tried snapping the heatsink with two pairs of diagonal cutters, though the metal is too soft and there's not enough space to get a purchase on it. I tried dremelling it, though I was worried about the heat it was generating. Once I'd given up on those methods I tried the most obvious thing and simply pushed the diode out of its heatsink using the blunt end of a plastic ballpoint pen. It slid out very easily, though I may have loosened the glue with my previous attempts.
On the diode, there's a tiny little 2d barcode, too small to be legible at all, I can't even tell what encoding it is because it's too small to really see, but I imagine it's probably a micro QR code. There's no way I could possibly get a picture of it, the only camera available at the time was this cellphone, and since then I've mounted it in a host and the capacitor obscures the barcode.
Like all harvests, I used an antistatic grounding strap through the operation... If you don't, you'd probably want to solder the pins together so you don't discharge static into the diode.
I've hooked it up to a custom driver running at 300mA, mounted it in a jayrob sidebutton host, along with a jayrob "G1" lens, and I'm pleased to say it's burning black marks in my white painted wall from 20 feet away. It can burn a 1mm hole in a black floppy disk in about 45 seconds *unfocused*!!! Times like these I really wish I had a LPM.

Think you did a great job, are there any pics of the laser actaully running? I'd love to see it.
you got any readings?
