The entire pickup moves to do tracking.


The entire pickup moves only when the tracking error reaches a certain
point, at which time the pickup is bumped a bit, and the tracking coils
re-center. Unless we're talking about an old Philips pivoting pickup with no
tracking coils...

No, not those! Anything but those!

But I'm pretty sure you knew this anyway.

Right, it was in direct reponse to the original question but perhaps the
reply didn't quite make it intact. :-)
