Abstract

The invention discloses a holographic storage device and an operation method thereof. The holographic storage device comprises a light source module, a light guide module and an optical conversion unit. The light source module is used for providing at least one light beam. The light guide module is used for receiving the light beams from the light source module and guiding the light beams from the light source module to a storage disc. The optical conversion unit is optically coupled between the light source module and the storage disc and used for converting the light beams from the light source module into light beams to be projected in a point light source array mode. Through the optical conversion unit, diffraction light generated when the storage disc has displacement has enough intensity, so that the displacement tolerance of the holographic storage device to the storage disc is improved.

Description

technical field [0001] The invention relates to a hologram storage device and its operation method. Background technique [0002] With the development of technology, the required storage capacity of electronic files also increases. A common storage method is to record the magnetic or optical changes on the surface of the storage medium as the basis for the stored data, such as a magnetic disk or an optical disk. However, as the required storage capacity of electronic records increases, the technical development of holographic storage has begun to attract attention. [0003] Holographic storage technology writes image data into a storage medium (photosensitive material) after signal light and reference light interfere. When reading the data, the image data can be generated by re-irradiating the reference light onto the storage medium (photosensitive material). Then, the generated image data is read by the detector. However, during reading, the disc containing the storage ...
