Holographic storage medium and method and apparatus for recording and/or reproducing data to and/or from a holographic storage medium
Abstract:
A method and apparatus for recording and/or reproducing data to and/or from a holographic storage medium and a holographic storage medium therefor are provided. The method of reproducing data from the holographic storage medium, in which a hologram containing data is recorded through interference between a signal beam and a reference beam, the data being recorded in pages and a plurality of the pages being recorded in a book, includes controlling the reference beam so that an increasing/decreasing order of a reference beam in a current book which is currently reproduced is reverse to an increasing/decreasing order of a reference beam in a previous book which was reproduced before the current book, and reproducing pages of the current book from the holographic storage medium according to the controlling of the reference beam.
