    摘要: The present invention relates to a method for recording data pages in a holographic recording medium, and more specifically to a method for compensating for sensitivity variations of the holographic material of the holographic recording medium. According to the invention, a method for recording data pages on a holographic recording medium has the steps of: modulating a light beam with a spatial light modulator to generate a data page with data to be recorded, and applying a compensation profile to the data pages during recording for reducing contrast variations in the reconstructed data pages, wherein the compensation profile is determined from the irradiation history at the recording position and the sensitivity curve of the material of the holographic recording medium.

    摘要: A data page for optical data storage for an optical storage system, i.e. a holographic storage system, is presented. The data page includes one or more areas, which are less sensitive against a movement of the data page in a movement direction of the storage medium. A holographic storage medium comprising such data pages is presented. An apparatus for reading from and/or writing to an optical medium comprising such data pages, and to a method for reading and/or writing such data pages is presented.

    摘要: The present invention relates to a method for calibrating a holographic storage system, and to an apparatus for reading from and/or writing to holographic storage media and a holographic storage medium suitable for such method. According to the invention, the method has the steps of: sending a set of test data pages through at least part of the holographic storage system; receiving a set of transmitted test data pages with a detector; comparing the set of transmitted test data pages with the set of sent test data pages; and correcting parameter variations of the holographic storage system based on the results of the comparing step.
