HOLOGRAPHIC RECORDING AND/OR READ-OUT DEVICE AND HOLOGRAPHIC CARRIER

摘要

The invention relates to a holographic device for writing data in and/or reading-out data from a holographic information carrier. The holographic information carrier comprises a plurality of patterns recorded with a plurality of corresponding recording multiplexing parameters. The holographic device comprises means for detecting one of the patterns and means for associating the detected pattern with the corresponding recording multiplexing parameter. The invention also relates to a corresponding read-out method and a corresponding recording method.
