    摘要: Intensity profile correction for data pages for holographic storageThe 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, andapplying 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: It is known in the case of digital helical track recording and replay apparatuses for audio, video and general data to be recorded for pilot tones to be interleaved in the data tracks, for tracking. The interleaving can be carried out simultaneously with the data by frequency decoupling (a) or by superimposition (b). The invention is based on the object of providing a helical track recording and replay system which carries out tracking in a simple manner. According to the invention, the ATF signal is obtained in a filter module, which also carries out the rectification of the filtered-out pilot tones. The two DC voltage levels are interrogated and processed in the servo microcontroller, with A/D converters. Coupled to the rotation of the head drum, pulses are produced by the servo system which switch the ATF conditioning over between direct operation and tracking operation, so that evaluation is achieved by the microcontroller during the fast ATF burst phase.
