Wow so many feedback!
As I thought, it is out of my field to actually change the mechanical motion. However, the ultimate goal is not to actually change the polar coordinate system to a Cartesian coordinate system but just to gain control of the way pits and lands are created. It is my fault...
Hello, I would like to modify the optical driver burner. Where can I find schematics, circuit designs and such? I would like to modify the photolithography process to move freely rather than be fixed to a polar coordinate. I am fairly new to EE. Any help would be appreciated.
