摘要： An object of the invention is to provide an optical pickup apparatus which, using a single optical system having a large NA objective lens, can compensate for the spherical aberration caused due to manufacturing errors in the thickness of recording media, as well as the spherical aberration caused due to the recording surface position in the thickness direction which differs depending on the type of recording medium, and can thus perform recording or playback on different types of recording media. A lens assembly having a plurality of lenses each of which is independently displaceable along its optical axis is interposed between a light source and an objective lens, and the lenses in the lens assembly are moved by a lens driving means independently of each other along their respective optical axes in such a manner as to reduce a spherical aberration caused due to the thickness of the light transmitting layer of the recording medium and spherical aberrations on optical surfaces of the optical system.

摘要： A two-group lens is comprised of a first lens and a second lens. The first lens is driven in an optical-axis direction by a magnetic circuit including a variable-distance use coil. As the first lens is driven, the second lens is also driven in an opposite direction to the first lens by a magnetic circuit including a mass-body driving coil, where the center-of-gravity position of movable part of an objective lens driver is kept at a generally constant position. The variable-distance use coil is disposed with the same gap as the mass-body driving coil. Thus, the distance between the first lens and the second lens can be held constant with a simple structure, without involving any complex structure, so that an accurate tracking can be achieved.

摘要： A novel titanyl phthalocyanine crystal, a photoconductive material comprising the same, and an electrophotographic photoreceptor using the same are disclosed. The titanyl phthalocyanine crystal has a primary particle diameter ranging from 0.03 to 0.15 &mgr;m, shows a maximum X-ray diffraction peak at a Bragg angle (2&thgr;±0.2°) of 27.3°, has a ellipsoidal tabular form, and has a BET specific surface area of not less than 35 m2/g. The crystal has improved crystal form stability against solvents and holds its crystal form for an extended period of time in a dispersed and coated state. An electrophotographic photoreceptor using the crystal as a photoconductive material is excellent in sensitivity, stability, and durability.

摘要： In accordance with the present invention a pickup device for optical disks includes spring wires supporting displaceably in focusing and tracking directions a lens holder holding an objective lens. One set of more than two spring wires is provided for each side of the lens holder and a total of two such sets of spring wires are arranged parallel to each other. Of more than two spring wires of each set, at least one spring wire has a cross section allowing a spring constant in the focusing direction and that in the tracking direction to vary from each other and is also positioned farther or closer than the remaining spring wires away or to a centerline of the objective lens. As such the pickup device can ensure a sufficient displacement in the focusing and tracking directions and also control an inclination of the lens holder.
