My understanding is that the writer cuts grooves
at various depths underneath the surface as a way
to record data. Is that wrong? In any case, it cuts
some kind of marks in plastic. It's not just magnetic
storage.

It's not cutting grooves. It's pitting. And it's not cutting the
plastic. It's making these marks on the media sandwiched between the
two layers of plastic; one on the top, the other on the bottom.
