Not sure why oo-toob threw this one up though I do remember the Doomsday book fondly as i helped collating some submissions from a school way back when.
Obsolete technologies can be fun and this clip contains two.The then quite new CD-Video which combined a few tracks of digital CD-compatible audio with a single track of analogue laserdisc compatible video.
Johnny “think of a number” ball points to the laserdisc and says “digital” which is wrong as laserdisc was analogue and this pits and lands on the disc were ma modulated analogue signal. It’s true that digital audio could be stored there too but the BBC Doomsday project which used a laserdisc to store images and video accessed through a computer was storing analogue information.
Anyway I always thought laserdisc would’ve been a better vinyl record replacement because it could store analogue audio alongside digital in a 12″ for factor thus keeping the lovely album artwork.
Sony’s prototype compact disc was also 12″. Sadly Philips won out and the hard-to-love CD was born.
