CD Grooves experiment Aim: Determine the number of grooves per cm on a CD Theory review The groove spacing is also called the "track pitch". It is the distance between each track. the shorter the wavelength of the laser light they use the closer they can make the grooves and the more information they can get on the disk. Also notice however that the track pitch decreases more rapidly than the wavelength of the lasers in the above table‚ this is because you can also reduce the track pitch
