Compact discs/dvd

You’ve probably got quite a few CDs in your collection — but how do these shiny plastic discs work? In this BrainPOP UK movie, Tim and Moby teach you the basics of compact disc technology. In this educational, animated movie you’ll discover how binary code, a sequence of ones and zeroes, is used to record music onto CDs. Learn how CD players use lasers to read this sequence and decode it into music, and how CD-ROMs and DVDs use technology that’s remarkably similar. So take off your headphones and get ready for a compact lesson on CDs!
