    Abstract: The present invention relates to a head arrangement for reading a magneto-optical recording medium (10) comprising a storage layer and a read-out layer. The head arrangement comprises an improved field generating means for generating a magnetic field used for copying a written mark from said storage layer to said read-out layer upon laser heating, the field generating means being arranged to generate a predetermined field gradient and/or a predetermined local maximum in a field component perpendicular to the surface of the recording medium (10). The width of the spatial overlap can thus be reduced such that an improved resolution and/or power marginis obtained.

    Abstract: The invention relates to a probe tip that is transparent to light, for emitting and/or receiving light in a specific manner, for use in an optical analyzing or processing system for examining and/or processing surfaces with an optical resolution in the sub-light wavelength range. The inventive probe tip has a body (5) consisting of a light-conductive material, with a surface that is coated with a light-absorbing layer (2). Said layer is interrupted by at least one through opening (3), through which the light passes. The invention also relates to a method for producing the probe tip. The invention is characterized in that the through opening in the layer is completely filled with the light conductive material and in that said light-conductive material finishes flush with the light-absorbing layer or protrudes beyond said layer. The inventive probe tip can be used in the fields of near field microscopy, optical photolithography and in magnetic/optical memories

    Abstract: A monolithic optical head (200) facilitates reading and writing optical data on an optical recording medium. The optical head (200) includes a monolithic substrate (210) formed of an optically transparent material. The substrate (210) has a first side (212) and a second flat side (216) opposing the first side (212). The first side (212) includes a central region that has a curved surface (220) to produce a lensing effect, and a peripheral region (201). The second flat side (216) has a central portion opposing the curved surface to couple radiation from and to the curved surface through the substrate. The second flat side (216) also has a peripheral portion opposing the peripheral region of the first side (212).

    Abstract: A magneto-optical recording/reproducing apparatus which comprises a first optical system (1) provided with a first objective lens (2), a second optical system (21) provided with a second objective lens (22) having a numerical aperture different from that of the first objective lens, and a magnetic head (19) that is provided close to a magneto-optical recording medium for recording and is driven together with the second objective lens (22) in a body. Even when either of a first and a second magneto-optical recording medium (41, 42) having recording densities different from each other is loaded in the magneto-optical recording/reproducing apparatus, the recording or reproducing thereof is possible. Therefore, the compatibility between the first and the second magneto-optical recording medium (41, 42) is obtained.
