There is a review (that I can't locate) that explained how a laser reads the physical pits and grooves of a CD. It's being done in an analog fashion ( a mechanical process) which then had to be processed into the digital domain.
With the laser just reading a painted pit and groove, there is less chance of error. Physical pits and grooves aren't as well done as they should be when stamped. A painted one can be very precise, comparatively.
All the best,
