摘要:
An optical recording medium including two or more recording layers which are capable of transmitting at a high transmittance recording light or reproducing light for performing recording/reproducing of a first recording layer (3) without having to make the thickness of a second recording film (5) positioned towards the side from which the recording light or the reproducing light enters. An optical recording medium including two or more recording layers, and which includes the first recording layer (3), the second recording layer (5) positioned further towards, with an intermediate layer (4) in between, the side from which the recording light or the reproducing light enters than is the first recording layer (3), and includes, between the above-mentioned intermediate layer (4) and the above-mentioned second recording layer (5), a dielectric layer (7) for increasing the transmittance for light passing through the above-mentioned second recording layer as the incident angle of the light becomes greater.

An optical device used for converging a light beam on a signal recording surface of an optical disc includes an optical lens for converging the light beam on a signal recording surface of the optical disc and a light barrier portion provided on a surface of the optical lens facing the optical disc. The light barrier portion includes a light transmitting aperture through which is transmitted the light beam converged by the optical lens. The light beam illuminated on the optical disc has its diameter controlled by this light transmitting aperture. The light radiated by a light source so as to be incident to the optical device is converged by the optical lens. The light converged by the optical lens is transmitted through the light transmitting aperture and illuminated on the signal recording surface of the optical disc. The diameter of the light beam illuminated on the signal recording surface of the optical disc is controlled by the light transmitting aperture, and thus the numerical aperture NA of the optical device is determined.
摘要:
An anti-reflection coating layer is formed on the surface portion of a recording medium. This enables to obtain a margin for the air gap thickness change when recording/reproducing an information signal using the “near-field technique” as well as minimize a data loss caused by a collision. Furthermore, the present invention provides a film configuration which can easily be produced.

摘要:
A method for splitting a piezoelectric device used in substitution for dicing for shortening the processing time as compared to a case of using the dicing to improve productivity to enable the shape of the piezoelectric device more suited to the emission shape of a solution to be achieved, and a method for manufacturing a printer device whereby a narrower nozzle pitch may be achieved. A resist 201 is formed at a pre-set position on a major surface of the piezoelectric device 43 bonded to a vibrating plate. Using this resist 201 as a mask, powders or particles are sprayed onto the piezoelectric device 43 for removing the portion of the piezoelectric device 43 not carrying the resist 201 to form the piezoelectric device 35 of a desired shape at a pre-set position.
摘要:
An optical lens whose focal length is different on first and second planes perpendicular to each other is provided. The optical lens is configured such that a convex element, which is formed integrally with a substrate having a flat face, has a convex curved face that functions as an optical lens and is shaped such that the curvature on a first cross section and the curvature on a second cross section perpendicular to and intersecting with the first cross section are different from each other, whereby the focal lengths on the first and second cross sections are different from each other. A groove of a substantially elliptical shape or a substantially rectangular shape is formed along the boundary between the substrate and the convex element. The optical lens is used to produce a focus error signal or is incorporated into an optical pickup apparatus.
