摘要： The optical recording medium has a recording layer sensitive for recording at a first wavelength and sensitive for reading at a second wavelength, the recording layer having a groove structure, wherein at the first wavelength the groove structure has a diffraction efficiency into a first diffraction order sufficiently large to generate a push-pull signal, and at the second wavelength it has a diffraction efficiency into a first diffraction order close to zero. The optical pickup for recording on an optical recording medium intended to be read with a second wavelength and a second numerical aperture is characterized in that it has a light source for generating a light beam at a first wavelength and a numerical aperture given by the second numerical aperture multiplied with a ration of the first wavelength and the second wavelength.

摘要： A holographic storage system having an improved data page quality is described. The holographic storage system includes a special optical filter or a special light source for emphasizing the high frequency components of a reference beam and/or an object beam. This is achieved by an optical filter arranged in a Fourier plane, which has a higher attenuation at the center than at the edge. Alternatively, an adapted light source for generating the reference beam and/or the object beam is arranged in a Fourier plane. The light beam emitted by the light source has a higher intensity close to the edge than at the center.

摘要： An apparatus for reading from a multilayer holographic storage medium with a coaxial arrangement of a reference beam and a reconstructed object beam is described. The apparatus has an objective lens for focusing the reference beam into the multilayer holographic storage medium such that the reference beam has a focal point behind or in front of a reflective layer of the multilayer holographic storage medium, wherein a distance between the objective lens and the multilayer holographic storage medium is set in accordance with an addressed layer of the multilayer holographic storage medium, and an imaging system with a fixed lens of focal length f and a movable lens of focal length f for re-collimating a reconstructed object beam, wherein for a specific position of the movable lens the imaging system assumes a 4f configuration. For re-collimating the reconstructed object beam the apparatus is adapted to shift the movable lens of the 4f imaging system by substantially twice the shift of the objective lens necessary for addressing a specific layer of the multilayer holographic storage medium.

The objective lens comprises a lens, an optical element having a variable refractive index and a solid immersion lens, which are disposed on a common optical axis, wherein the optical element is arranged at a convex side of the solid immersion lens and has a top and a bottom surface arranged adjacent to each other in a direction of the optical axis, the bottom surface having a concave shape that is adapted to the shape of the convex side of the solid immersion lens and the top surface having a curvature that is lower than a curvature of the convex side of the solid immersion lens, and wherein a difference between a refractive index of the optical element and the solid immersion lens is small in the far-field mode so that the solid immersion lens and the optical element act substantially as a single optical element in the far-field mode, whereas the difference is large in the near-field mode so that the optical effect of the solid immersion lens is significant in the near-field mode.

摘要： When an optical recording medium having a plurality of data layers is being read from and/or written to, the input beam experiences an aberration, inter alia in the top layers of the data layers. In order, nevertheless, to achieve a high data density, a device for correcting the spherical aberration is located in the beam path of the input beam. In the case of the use of an optical diode in which the input beam and the reflected beam have directions of polarization perpendicular to one another, such a device is expensive to implement and associated with a reduced optical efficiency. It is an object of the invention to propose an apparatus for reading from and/or writing to optical recording media, in the case of which a high optical efficiency and balancing of the spherical aberration are achieved with low outlay. For this purpose, the device for correcting the spherical aberration is set up such that the reflected beam traverses it uninfluenced, whereby means for correcting the imaging of the reflected beam onto at least one detector unit are provided in the further beam path.
