How does a laser read a disk and translate it into sound/music?
The music is stored on the disk as digital data, or a series of 1’s and 0’s. The 1’s and 0’s are recorded as light and dark spots on the disk. The laser shines on the disk and reflected back to a sensor. As the disk spins under the laser the light and dark spots go under the laser and make it’s reflected beam turn on and off. This is picked up by the sensor that turns it back into digital 1’s and 0’s. These are put back together and translated back into music.
