My "gut feeling" is that any further improvement in the error correction
mechanisms is likely to be well beyond the point of diminishing returns.

On the other hand, efforts to improve the laser tracking servos would be
very worthwhile. The only time I've heard audible clicks or mutes from my CD
player is when the servo jumps a track, either due to a defect on the disc
or physical vibration. No improvement in the error corrector can handle
this.
