" Stamped CDs work by the pits being 1/4 of the light wavelength deeper, causing the light to null out. Burned CDs work by a photographic layer that blocks the beam to emulate those pits. Static is not geerally a problem. "The CD system does not work like that. What does " causing the light to null out" mean?
CD "works" at the light level you appear to be referring to by sensing the phase difference of the reflected laser light from the pit compared to that from the land.
The CD itself is prone to storing static electricity being made from polycarbonate. The optical collimator lens assembly is mounted in a very sensitive assembly that moves up and down to keep focus as the disc rotates. It is very lightweight and could feasibly be attracted by static electricity (just like paper to a charged plastic surface) to the disc causing it to adjust to keep focus which may affect the sound (additional demand on the power supply?). So using any form of de-static device including a Zerosat could help improve matters.
