摘要： According to an embodiment, a light deflecting element includes a dielectric body, a first electrode, and a second electrode. The second electrode is configured to sandwich the dielectric body with the first electrode so as to apply a voltage to the dielectric body. The second electrode includes orthogonal portions that are substantially orthogonal to an incident direction of a light beam passing through the dielectric body, parallel portions that are substantially parallel to the incident direction of the light beam. The orthogonal portions and the parallel portions are formed in an alternate manner on the light beam incident side of the dielectric body. The second electrode includes a linear sloping portion that slopes in a direction toward intersection with the incident direction of the light beam. The orthogonal portions, the parallel portions, and the linear sloping portion are formed integrally.

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.

摘要： According to an embodiment, a light deflecting element includes a dielectric body, a first electrode, a second electrode, and a third electrode. Each of the second electrode and third electrode is configured to sandwich the dielectric body with the first electrode. The second electrode includes an electrode having a side that lies substantially orthogonal to an incident direction of a light beam, a side that is substantially parallel to the incident direction, and a side that intersects with the incident direction. The third electrode includes an electrode having a side that is aligned with the second electrode, a side that is substantially parallel to an incident direction of the light beam, and a side that intersects with the light beam, and that slopes in an opposite to that of the side of the second electrode that intersects with the light beam.
