Amazing Week, Day 1: Digital audio

Part of Amazing Week 2012 In 1981 I was watching the BBC TV show “Tomorrow’s World” when the CD player was first introduced to the UK. The presenter demonstrated the system, and showed how dirt and dust would simply rinse off the disc and it would still be completely playable. He talked about how the disc was read by a laser and would never wear out. I later read more about the system in hi-fi magazines.
