ABSTRACT:
A data writing and reading device is capable of writing and reading data with respect to a holographic storage medium. The data writing and reading device includes a light source which emits a laser beam, a focusing lens unit having a multi-focal lens which splits the laser beam into a reference beam and an object beam and projects the split beams to the storage medium so that an interference pattern between the reference and object beams can be written in the storage medium, and a photo detector for detecting the object beam when the object beam is reproduced in accordance with the holographic data with the incidence of the reference beam to the storage medium. With a simple hardware, data can be written to or read out from the holographic storage medium.
