How do music CDs work?
So how does a CD player or computer convert those billions of bumps into music? It takes a very precise laser beam focused on the data track as the CD spins rapidly around. As it does so, a sensor detects changes in the laser beam’s reflection, since the bumps cause the laser to reflect differently.
How does a DVD CD work?
DVD (digital video disc) is a technology based on optical data storage similar to compact disc (CD). Analog information is converted into digital information, which is then encoded onto the disc from the inside edge out. Digital data are encoded by means of pits on the recording layer of the disc.
How is data written on a CD?
CDs store information digitally, i.e., with the help of millions of 1s and 0s. Data on a CD is encoded with the help of a laser beam that etches tiny indentations (or bumps, if you will) on its surface. Hence, a laser beam can encode the required data into a compact disc using pits and lands (0 and 1, respectively).
