What is sound-on-disc?

Sound-on-disc is when you can play music or voices from a disc, just like how you might listen to your favorite song on a CD.

Imagine you have a record player, it spins a vinyl record, and that makes sound. Now think about a CD player, it reads a disc made of plastic, and that also makes sound. Both are ways to hear music, but they work a little differently.

A sound-on-disc system uses laser beams to read tiny bumps on the surface of the disc. These bumps represent the music or voices you're listening to. When the laser reads these bumps, it turns them into sound, kind of like how your phone turns dots on a screen into pictures.

You can put music or stories on a disc and play them anytime. It’s like having a magic box that stores your favorite songs or bedtime stories, ready to be heard just by pressing a button!
