The movable coil may be wound around the one side of the yoke and a guide member movable in the radial direction of the optical information recording medium. A shorter side of the movable coil may be located below the moving part of the objective lens and no constructional portion may be located above a longer side of the movable coil.

摘要： An optical pickup device for an optical disk having a recording surface comprises a stationary optical system having an incident optical axis, which is parallel to a radial direction of the optical disk. The stationary optical system is adapted to transmit a light beam emitted from a light source along the incident optical axis. A carriage is provided for linear movement in a seeking direction along the incident optical axis of the stationary optical system. A deflecting member is secured to the carriage and has a deflecting face for receiving the light beam transmitted from the stationary optical system along the incident optical axis and for deflecting the same toward the recording surface of the optical disk. An objective lens for converging the light beam deflected by the deflecting member on the recording surface of the optical disk and for leading a light beam reflected by the recording surface of the optical disk toward the deflecting member, is supported on the carriage and disposed between the deflection member and the optical disk. The distance between the deflection point of the deflection prism and the center of the objective lens is approximately twice the focal length of the objective lens.
