    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: An optical element and manufacturing method of the present invention prevent the incidence of light on unnecessary portions of the optical element so that stray light and noise are eliminated. The optical element is configured from 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: A polarizing beam splitter (21) is secured in a state wherein a bottom plate (2102) thereof contacts closely with an upper face of a substrate (16) and a light receiving element (23) without a gap left therebetween. A quarter-wave plate (17) is attached to the polarizing beam splitter in a state wherein a lower face (1702) thereof contacts closely with an upper face (2104) without a gap left therebetween such that the lengthwise directions and the widthwise directions of them coincide with each other. An objective lens plate (18) is attached in a state wherein a lower face (1806) thereof contacts closely with an upper face (1704) of the quarter-wave plate without a gap left therebetween. A light source (22) is bonded at a mount member (22B) thereof to the upper face of the substrate by means of a bonding agent or the like such that an emitting face of a semiconductor laser (22A) and a front face of the mount member contact closely with a portion of a side face (2106) of the polarizing beam splitter without a gap left therebetween.

    摘要: A disc cassette comprises a case in which a recording disc is rotatably received. The case has an opening through which the disc is exposed. A bridge defined by the case extends across a mouth portion of the opening. A slide bar is arranged beside the bridge in a manner to move axially therealong. A shutter is connected to the slide bar to move therewith. The shutter selectively opens and closes the opening in accordance with axial movement of the slide bar. The slide bar has a base portion which comes beside the bridge when the shutter takes the open position, and the base portion is formed with a recess which faces in a direction away from the center of the disc recording medium.
