摘要： A phase-conjugate holographic data storage device capable of enhancing the characteristics of recording and reproducing data by using a focusing lens is provided. The holographic data storage device includes a focusing lens which focuses an object beam having data, a spatial light modulator which is located on the optical path of the object beam passing through the focusing lens and modulates the object beam, and a data recording medium which records an interference pattern generated by interference between a reference beam and the object beam passing through the spatial light modulator and converging into a focus. The focusing lens is a focusing lens having at least two different focuses. The holographic data storage device is capable of effectively reducing a dc term having a bad influence on the characteristics of recording data, minimizing the size of a data unit, that is, a spot, and thus enhancing the density of recording data.
