> Laser discs are not digital... It is digitized in the time domain
Laser disks are 100% digital (as you said, they store digits in the time domain).
They don't encode their data using binary like a CD does.
"Binary" and "digital" are two separate and unrelated concepts.
Um... I think they store "PCM encoded-ish" but the length of the pits are not discrete on / off like on a CD but various arbitrary lengths, so analog.
The sound was also analog to begin with, then the same encoding as CDs, then after that AC-3 and DTS.
