Abstract
A holographic storage medium, and a method and an apparatus for recording/reproducing data on/from the holographic storage medium, the method recording data on the holographic storage medium as holograms recorded in datapages, and dividing one of the datapages into a plurality of regions; and recording the data at various sampling rates in the respective regions.
Claims30
A method of recording data on a holographic storage medium as holograms recorded in datapages, the method comprising:
- dividing one of the datapages into a plurality of regions;
- and
- recording the data at various sampling rates in the respective regions.
An apparatus for recording data on a holographic storage medium as holograms recorded in datapages, the apparatus comprising:
- a light processing unit which records the data on the holographic storage medium using a signal beam and a reference beam;
- and
- a control unit which controls the light processing unit so as to divide one of the datapages into a plurality of regions and record the data at various sampling rates in the respective regions.
A holographic storage medium including holograms recorded in datapages, wherein one of the datapages is divided into a plurality of regions, and data is recorded at various sampling rates in the respective regions.
A method of reproducing data from a holographic storage medium in which holograms are recorded in datapages, the method comprising:
- reading the data from the holographic storage medium;
- distinguishing a plurality of regions in the datapages;
- and
- processing the respective regions at various sampling rates in order to reproduce the data.
An apparatus for reproducing data from a holographic storage medium in which holograms are recorded in datapages, the apparatus comprising:
- a light processing unit which reads the data from the holographic storage medium;
- and
- a control unit which distinguishes a plurality of regions in each of the datapages and processes the respective regions at various sampling rates in order to reproduce the data.
