摘要： An optical pickup device and optical disc apparatus of the present invention include an optical element that prevents the incidence of light on unnecessary portions of the optical element so that stray light and noise are eliminated. The optical element include at least one substrate having a plurality of lens substrates that have embedded lenses made of a material with a higher refractive index than the at least one substrate. A shielding means limits the optical path so that incident light propagates only within a prescribed optical path formed on a light incidence-side or emission-side surface of one of the lens substrates. In addition, the shielding means is formed from an absorptive or reflective film placed in a region outside the prescribed optical path or through machining the region outside the prescribed optical path.

摘要： The influence of dust is reduced to prevent degradation of the recording and reproduction performances of an optical head apparatus and an information processing apparatus which use a flying slider. The optical head apparatus includes a slider (28) for being flown by an air flow produced by rotation of a disk-type recording medium. Parallel rail elements (28A, 28B) are formed along the direction of the air flow on an opposing face of the slider to the disk-type recording medium. Another rail element (29) is formed in the middle between the two rail elements, and beam light condensed by an objective lens passes through the rail element (29) formed from a transparent material. Even if a foreign particle flows into a gap between the slider and the disk-type recording medium, the optical influence of the foreign particle is less likely to be exerted.

摘要： A deformable mirror device compensates the spherical aberration caused by the difference of thickness of the cover layers covering recording layers of an optical disc. Circular projections are concentrically arranged on a flexible member (2) where a mirror surface (3) is formed to produce a strength distribution pattern (2a). Attractive force is generated as electrostatic force between an upper electrode (8) and a lower electrode (9) according to the voltage applied from a drive circuit (10) so as to contract the second space (7) and accordingly expand the first space (5) in order to deform the mirror surface. At this time, the profile of the mirror surface is deformed to show a desired profile that can compensate the spherical aberration by the pattern formed on the flexible member (2) as strength distribution pattern (2a). With this arrangement, only a single drive actuator (10) is needed to deform the mirror surface to simplify the configuration and the control operation. The mirror surface can be deformed stepwise to show predetermined deformed profiles depending on the pattern formed as strength distribution pattern (2a). Then, it is possible to compensate the spherical aberration for each of the three or more than three recording layers of the optical disc.
