The London Science Museum offers an exhibit on how CD’s work, it’s a great lesson for all

How a CD works

One of my colleagues took a trip with his family to England recently. Being an engineer and a good father, he wanted the trip to be both fun and educational, so he went to the London Science Museum with his family. While there, he discovered a lovely exhibit that discussed the inner workings on how a CD works. We may feel like CD technology is old and outdated, but it’s still a modern miracle of science on how a laser is used to read such minute Pits and Lands to hear music, read files, or watch videos. In fact, the below short video highlights just how simple the concept is, but how incredible it is to create.
