Any attempt to dump disc real raw binary data?

Hi there,

I've recently studied the in & out of how data are layered onto a CD-ROM surface by reading the ECMA standard.
I realized that the binary data you get from CD drive are actually not the binary raw data burnt onto the physical material:
Sector data first get scrambled before being transformed into F1-Frames, then into F2-Frames and into F3-Frames. Finally, F3-Frames are encoded through 8-to-14 Modulation (EFM) before getting burnt.
So when a CD drive is reading raw data, the firmware goes through all this process backward to send unscrambled sector data to the computer.

Did anybody make any attempts to modify the firmware of a disc drive and get the binary raw data instead of the sector data?
