About DVDs

Music CDs and DVDs have grooves (tracks) in which the digital
data is recorded. The data is represented as microscopic pits
recorded into the track – these pits are read by a laser beam to
play the disc. On DVDs, the density of the tracks and pits is
twice that of CDs, so DVDs can contain more data in less space.
