It doesn't matter how it's made but how to replicate! And to do that, you need a perfect raw binary readout. Then you can use special cpu(s) to interpret from memory-card/hdd to faked disc.
It is all in the pressing: http://www.cdrinfo.com/Sections/News/Details.aspx?NewsId=15194
Seems if you can't modify firmware you have to replicate pressing.. problem is the data you need to replicate in under ROM Mark encryption.

It's a protection against re-pressing, not against emulating! But of course, the emulation would require heavy computing resource, but it's not impossible. I'm talking about raw physical emulation: feed the laser-sensors with the appropriate signals.
The downside is that the whole thing will be in vain if at least the retail-to-debug conversion succeed. And this is a lot of trouble for so little goal.
So we talk about pirate-pressings? If so, then the problem is the huge amount of overhead and the precision required for repressing. Due to the fact that from mater-disc to pressing negative the transition done by chemical reactions make the production cost relative low compared to highly sophisticated equipment needs to replicate the images read by the microscope. Just think about how complex the entire disc-reading mechanism is and to be as accurate as the original you need resolution higher than the original by multiple times.
(in compare: with nuclear accelerators you can make gold from lead, but the costs so huge that it makes no sense.. in terms of gold-making)
They seem to be efficient and competent when it comes to reverse engineering and manufacturing. I could almost see them engineering some form of cheaper automatism to do this and putting it out on global markets even with the R&D required.

"Pirates" for the most part work off the ideas of others. For example: if you go to China Town to buy Iron Man 2, you aren't getting their work but rather another's telesync they simply downloaded from torrents. Same with software. Hardware is a bit of a different story.
Anyways, the reason companies use presses to make data discs is because of how amazingly cheap it is on an industrial scale, those machines press fast and can produce the millions of game copies necessary. There is no doubt it is possible to get a raw dump from a BD drive and then a raw burn. It is a matter of writing the driver to not attempt interpretation and rather read just etches, or its binary translation. Then, make it etch that exact data back.
Now, as to why it hasn't been done for the ps3: I'm fairly confident it has, it just isn't public. Surely there are people out there just like me, but with more money. If I am correct in this assumption, it has already been done.
So, I have dealt with a lot of electronics, and I've dealt with lasers. But, never have I dealt with optical data (the nuts and bolts). I COULD do it, but it would take a long time, because I have a lot to learn, and that wouldn't be the smart way to do it. However, I proposed this idea to, perhaps, give someone else with this specific expertise the opportunity to do it. I could write a program to search for the boot sectors in the disc, but so could anyone else. So once again I'm not much practical help.
As far as the driver experts mentioned above, I tried to join to contact them and couldn't. I will try again some other time. I currently have a pretty hefty RF project I'm working on, so...
Sorry to bump this old thread, however I've come across something in my recent travels on ebay.
If you have 20K to spend on it, then check this out:
And here I thought that we had established that an electron microscope is useless for replicating BD-ROMs
