    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 one embodiment, there is provided a camera module formed with substantially the same scale as a chip of an image sensor, includes a lens held by a lens holder, an image sensor placed in a position in which an image is formed by the lens, and a wiring board disposed between the lens and the image sensor and electrically connected to the image sensor. An opening that permits light entering the image sensor to pass therethrough is formed in the wiring board. Further, a passive component is contained in the wiring board.
