    摘要： An optical head apparatus for recording and reproducing data to and from optical disks, the apparatus boosting recording density by use of an objective lens with a higher numerical aperture (NA) than ever. A phase plate is added to the pupil position of the objective lens or to a position close thereto. The phase plate arrangement provides a deeper focal length, reduces the adverse effects of aberration and eliminates the need for a tilt servo mechanism despite the use of the objective lens having a greater numerical aperture than before.

    摘要： The adverse influence of reflected light from adjacent layers as stray light on a control signal or data signal is reduced when tracking a multilayered optical disc using differential push-pull method. The reflected light from the optical disc including stray light from an adjacent layer is once condensed with a condenser lens having little aberration and is then reflected by a reflecting mirror having a partial reflecting region. The resultant reflected light, which has the influence of stray light reduced, passes through a polarization beam splitter and becomes incident on a four-quadrant detector (for main beam) and a split detector (for sub beam) via a condenser lens having astigmatic aberration.

    摘要： When tracking a dual-layer optical disc by a differential push-pull method, the adverse effect of the reflected light from an adjacent layer, which produces stray light, on a tracking control signal is prevented. A split wavelength plate 20 is inserted in the optical path of the reflected light from the optical disc including the stray light from the adjacent layer so as to detect a region having no interference with the stray light with a four-quadrant detector, and then a push-pull signal by a sub-beam is formed.

    摘要： An optical pickup apparatus aiming at reduction of adverse effect on a tracking control signal and a data signal by preventing the reflected light from the adjacent layers of a multilayer disc changing to a stray light. In this optical pickup apparatus, the reflected light from the optical disc including the stray light from the adjacent layer is once focused with a focusing lens and is then reflected with the reflection plate. A flat attenuation element is provided between the lens and the reflection plate parallel to the optical axis with inclusion of the optical axis under the condition separated from the reflection plate. The reflection plate reflects the reflected light from the relevant layer and the attenuation element shields the reflected light from the adjacent layer. The light returning to the focusing lens includes less influence of the stray light. This light is detected with a detector to become a control signal and a data signal.
