Huh. I grew up with laserdiscs and never knew it was an analogue recording and not a digital one.

That explains some things for me.

Later Laserdiscs (and VHSs) had digital audio embedded in the analog audio stream the same way the GameCube and the Wii (and some N64 games) did it with Dolby Pro-Logic. But the video was always analog. IIRC the first widely available digital video format was Video-CD but that never took off in the west.
Are you being serious? If not, I’ll say that laserdiscs and CDs are digital. There is a physical representation of 0 and 1 which is pits and lands. A pit is like an indentation burned by the laser, and a land is a lack of an indentation. A pit represents a change from 0 to 1 and a land represents no change. So instead of a pit representing 0 or 1 it represents a change from the previous value.
