摘要： In a recording and reproducing apparatus, an optical disc is rotated in a rotating direction and an optical system focuses a laser beam on the optical disc to form a beam spot on the optical disc. The optical system is provided with a scanner which deflects the laser beam along a radial direction of the optical disc in such a manner that the beam spot follows a first scan trajectory along a first direction crossing the rotating direction and a second scan trajectory along a second direction different from the first direction. A first data track with a sequence of recording pits along the first scan trajectory is formed and arranged on the optical disc.
