    摘要: In an optical head for reading information signals out of a plurality of information tracks on an optical record medium by projecting a slit-like light spot onto the optical record medium, a laser beam having a substantially elliptical cross section is passed through a stop having an aperture to shield both edge portions of the laser beam to obtain a laser beam having a uniform distribution. Then, the laser beam emanating from the stop is made incident upon a cylindrical lens have a negative power in a direction of a major axis of the laser beam to form a laser beam having a uniform distribution in a longitudinal direction. The thus obtained laser beam is projected onto the optical record medium by an objective lens such that the longitudinal direction of the slit-shaped laser beam spot is aligned with a direction substantially perpendicular to a track direction in which information tracks extend. In this manner, a plurality of information tracks are simultaneously illuminated uniformly, so that it is possible to obtain a plurality of information signals having substantially the same level.

    摘要: A beam-spot control unit is arranged such that a light beam is irradiated onto an optical recording medium having a plurality of tracks, through an objective lens, to detect reflecting light of beam spots formed on the tracks by three or more photo detecting elements which are arranged in a direction corresponding to a track transverse direction. From a tracking error signal which is generated by a difference signal of pairs of photo detecting elements which are selected by a selecting switch from these photo detecting elements, a control signal is generated which positions the beam spots to a plurality of recording lines within a single track. A tracking control mechanism is utilized to enable positioning of the beam spots to a plurality of recording lines within the single track to be performed.
