How do CD drive motors work?

CD drive motors operate using electromagnetic principles to spin the disc at a constant speed. When a CD is inserted, the motor engages to rotate the disc while a laser reads the data encoded on its surface. The motor's speed is controlled by the drive's circuitry, which adjusts power to maintain a consistent rotation, typically at varying speeds depending on the position of the laser. Sensors ensure accurate tracking and positioning of the laser over the disc's data tracks.
