    摘要: The present invention relates to a holographic storage system, and more specifically to a method for pixel detection in a coaxial holographic storage system.In a holographic storage system according to the invention, with a coaxial arrangement of an object beam and a reference beam the bright pixels within the object beam have a phase shift of essentially π0 relative to the reference beam. For readout of a data page contained in a reconstructed object beam a detector detects an interference pattern generated by the interference between the reference beam and the reconstructed object beam.

    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 is the center.

    摘要: The invention relates to a suspension arm actuator for a plurality of directions of motion, which comprises a suspension arm designed as a two-arm lever and supported against a support and mounted to said support such that it can be pivoted, said suspension arm supporting on one of its lever arms a component that has to be actuated or being operably connected to such a component and being provided with a magnetic drive on the other lever arm for initiating a first swivel motion about an axis extending perpendicularly to the suspension arm, with a magnetic drive being allocated to said suspension arm for initiating a motion perpendicularly to this swivel motion. The invention solves the problem of designing such a suspension arm such that the latter's design is less complicated and laborious. To achieve this, the two magnetic drives are combined in the magnetic drive which is arranged on the lever arm facing away from the component, and this single magnetic drive is formed such that it generates an inhomogeneous magnetic field which allows initiating both the first swivel motion of the component and the motion of the component perpendicularly thereto.
