How does music get stored on a compact disk?

Answer 1

Data or music at the lowest level can all be represented by bits.Bits are either 0 or 1. The 0 bit is represented by burning a pit on the CD surface using a laser. The information on a standard CD is encoded as a spiral track of pits moulded into the top of the polycarbonate layer.The areas between pits are known as lands (1 bit). Each pit is approximately 100 nm deep by 500 nm wide, To grasp the scale of the pits and land of a CD, if the disc is enlarged to the size of a stadium, a pit would be approximately the size of a grain of sand. The spiral begins at the center of the disc and proceeds outwards to the edge, which allows the different size formats available. If you find this info useul Please vote!!!

Answer 2

To explain it quite simply, a laser is used to "burn" binary code onto the CD's surface. (like bumps in the CD blud) All this is, is a series of ones and zeros that when read by another laser and fed through the circuts circuits of a sterio stereo system get interpreted as sounds. For example: (and this is not real)

0110010100101010010010101011010101111010101010101101010101101110101010010101011110101101101011101011101010

This could be the binary code for what a snare drum sounds like. Given the multitude of sounds on a CD, there is milions upon millions of ones and zeros in different combinations to make a CD.

Answer 3

It is stored as binary code - etched onto the silver surface as microscopic 'pits' The laser reads the pits through the clear plastic covering, and converts the information back into music.
