摘要： An optical device is provided which has a light converging unit for converging the light illuminated on a magneto-optical recording layer of an optical recording medium and a magnetic field generating unit provided on the light converging unit towards the optical recording medium. The diameter of the light beam radiated on the magneto-optical recording layer of the optical recording medium is controlled by a light transmitting hole of the magnetic field generating unit. The light beam illuminated on the magneto-optical recording layer of the optical recording medium is not fluctuated in diameter so that it is possible to produce a magnetic field at a low power consumption. In addition, the magnetic field generating unit is not liable to be ruptured. There is also provided a recording and/or reproducing apparatus employing this optical device.

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.
