And, they were analog!
CDs, DVDs, and of course BluRays are digital, but laserdisc was analog.
I didn’t know that. Always assumed it was like a big CD.
Laserdisc had 4 audio tracks 2 digital and 2 analog. The digital tracks was what later became the cd. The analog tracks was often used by audio commentary along the movie and such.
Right??? I learned that about a year ago. I'm impressed they even made it work.
