Title: METHOD AND DEVICE FOR READING OUT HOLOGRAPHICALLY STORED INFORMATION
Abstract:
The invention relates to a method for reading out at least two holographic storage media. The aim of the invention is to provide a method and a device which allow to rapidly read out different holographic storage media by simple means. To this end, information beams (10a, 10b, 10c) from coherent electromagnetic radiation are produced in the at least two storage media (8a, 8b, 8c) using a reading beam (5, 7) and that said information beams (10a, 10b, 10c) are recorded using recording means (12, 14) to detect the information. The invention also relates to a corresponding device.
