    摘要: Disclosed is an optical system for an optical disk drive for reading/writing data from/in an optical disk. The optical system includes a light source emitting a parallel laser beam, a deflector having a rotatable mirror surface. The parallel laser beam emitted by the light source is incident on the mirror surface of the deflector and is deflected towards an objective lens system which faces the optical disk. A relay lens system is provided between the deflector and the objective lens system such that the mirror surface and a front principal plane of the objective lens system have a substantially conjugate relationship.

    摘要: An optical disc apparatus includes a fixed portion having a light source portion and a movable portion that holds an objective lens and moves along a radial direction of an optical disc. The fixed portion includes the light source portion for selectively emitting short and long wavelength laser beams, and a collimator lens for collimating the laser beams. The objective lens includes a positive refractive lens and a diffractive lens structure formed on a surface of the refractive lens. The diffractive lens structure has wavelength dependence such that spherical aberration varies in the undercorrected direction as wavelength of incident light increases. The objective lens converges the short wavelength laser beam of a predetermined diffraction order onto an informatlon layer of a thin cover type optical disc, and converges the long wavelength laser beam of the identical diffraction order onto an information layer of a thick cover type optical disc.

The periodic structure includes periodically arranged members made of material having different refractive index real parts. The core is surrounded by the cladding in the plane perpendicular to a wave-guiding direction. The Bragg angle obtained from the periodicity of the periodic structure is smaller than the total reflection critical angle at which X-rays are incident on the interface between the cladding and the core. The at least one period direction is the direction of at least one fundamental vector expressing the periodicity of the periodic structure in a plane of the core perpendicular to the wave-guiding direction.

    摘要: A photomagnetic head apparatus includes a beam splitter which splits a laser beam, reflected by concentric recording tracks of a rotating photomagnetic recording disc, into three bundles of rays. The three bundles of rays have different polarization directions in a plane which lies in a radial direction of the recording tracks. One of the three bundles of rays is used as a servo-signal light, and the remaining two bundles of rays are used as data signal lights. A defocusing diffraction element splits at least the servo-signal light into a least two bundles of rays in a direction corresponding to the tangential direction of the recording tracks, substantially perpendicular to the split direction of the beam splitter and which provides at least two split lights with a predetermined amount of positive or negative defocus in an optical axis direction. A pair of servo-signal light receiving elements receive the split beams of the servo-signal light produced by the defocusing diffraction element. A data light receiving element receives the data signal lights. The defocusing diffraction element is made of a non-circular element whose numerical aperture in the tangential direction of the recording tracks is smaller than the numerical aperture in the radial direction.
