Pits, grooves, whatever. I only used the CD as an example of a master
that's made with a laser to press a piece of plastic that's played with
a laser. You could play a phonograph record with a laser in several
ways, some of which are even in practice today, though too expensive for
even the most irrational audiophile. They're good for recovering sound
from "unplayable" records like lacquers where the lacquer coating is
peeling off the base material, or cylinders which are frequently eccentric.

But that's not to say that a less expensive system couldn't be developed
if there was a real need. Still, why would anyone want a complicated
mastering and playback system that won't buy you anything that a
properly mastered CD and a decent player will?

Well, just because, I guess.
